Fluid Dynamics Brochure
Fluid dynamics plays a critical role in many of the products that we encounter every day — from obvious applications such as water treatment systems and auto and aircraft aer odynamics to boundary-pushing usage in developing Olympic swimsuits, America’s Cup racing yachts, eco-friendly skyscraper HVAC systems, new plastic and glass materials, high-speed roller coasters, and leading-edge medical therapies. Behind the scenes, fluid dynamics is involved in the design and manufacture of hundreds of consumer, industrial and defense products. In any application that involves gas flow, liquid flow or heat transfer, fluid dynamics analysis can help deliver innovation and greater efficiency. ANSYS
Buyer’s guide for pre
As software applications continue grow ever more complicated, it becomes increasingly hard to communicate the essentials to prospective users. One proven approach is the buyer's guide, but not in its original form. That was one step up from the throw-aways handed out at trade shows. Those covered features, functions and benefits as if the product existed in a vacuum, as if the prospects had no other software.

Those old-style brochures and hand-outs were really distilled sales pitches. If that was not what the prospect needed to hear, the sales inquiry withered away. Everyone missed an opportunity.

Today, buyer's guides are vital but easily overlooked pieces of the infrastructure of engineering design and analysis. These new-breed guides are interfaces to the sales process. They are a crucial first step in deciding whether to upgrade existing capabilities or switch to something new.

A good example of this new type of buyers guide comes from Siemens PLM Software—its new "Buyer's guide for pre- and postprocessing software" used with finite element analysis (FEA) software. Siemens subtitled it, "What you need to know before selecting an FEA solution."

In its old form, this might have been another yawn-inducer. Instead, it is a compelling white paper. It is a thoughtful analysis of, and response to, questions prospects raise whenever they confront new technology. The buyer's guide meets these questions head-on. Even today, some software developers seem to hope these questions won't be asked till they get a signed P.O.

Siemens PLM also made sure the guide touched on all the issues. It was developed in coordination with a large distributor that has its own FEA offerings, with application engineers from Siemens and other firms, and with independent consultants who train FEA newcomers and solve tough FEA problems on a fee basis. Finally, the "pre- and post" buyer's guide is one a series Siemens tailors for prospects in different FEA situations.

Solving the Inherent
Transferring files between dissimilar systems can be a costly endeavor due to incompatible file formats. Traditionally, a loss of surface information occurs, rendering a model inaccurate. Valuable time and human resources are devoted to fixing the issues, while delivery schedules slip. In addition, as today’s engineering environments become more complex the need is greater than ever for accurate 3D file translation. Disparate systems need to be able to consume and work with the same data in different ways throughout the product design and engineering workflow chain. This paper offers the solution. Spatial

Integrated Analysis Achieves
At Modine Manufacturing Company in Wisconsin, U.S.A., designing charge air coolers and exhaust gas recirculation (EGR) coolers is largely driven by emerging emission standards in the United States and Europe. These new emission standards equate to higher thermal loads and more rigorous durability requirements for automotive engine and exhaust components. With the surge in demand for engine components that meet the new emission standards, it was apparent to Modine that it needed to conduct a greater number of concurrent engineering design projects without significantly impacting engineering headcount or physical test facility capital investment. Physical testing is expensive, and test capacity limitations make it nearly impossible to turn around a design project quickly and efficiently through testing alone. Given these factors, the need for leveraging the virtual environment was clear. ANSYS, Inc.

Early product failures and recalls are costly and result in loss of revenue, litigation, and brand devaluation among others. Hardware recalls are often costlier than software recalls as software patches can be easily downloaded and installed once flaws come to light. Why do recalls and early product failures happen over and over again? Becuase engineering teams are constantly under the gun to improve product performance, reduce form factors, and reduce time to market, all while cutting costs. In order to mitigate risk engineers need to develop a deeper understanding of the product behavior under real operating conditions and quickly evaluate design trade-offs based on overall system behavior.

Fast AND Reliable CFD
The pressures of global competition, complex requirements and shorter development schedules are forcing CFD engineers to do more in less time — without sacrificing accuracy. Accurate results help to prevent over-engineering along with its embedded costs. With high-fidelity CFD results in hand, engineers can design within smaller safety factors, which can ultimately reduce cost of a product or process. Conversely, poor-quality CFD results can lead to incorrect design specifications and increased development time. Accuracy and reliability of fluid flow simulation builds confidence that the solution will operate as intended, allowing shorter design cycles and quicker time to market. ANSYS

Modelling and Analysis
The ability to accurately model welding processes in order to predict residual stresses and distortions is becoming increasingly important in the engineering industry. Abaqus can be used to model the welding process but this has been found to be considerably time consuming and requires a large number of assumptions to be made. Virtual Fabrication Technology is an analysis software suite that is designed to allow Abaqus to accurately model complex welding procedures. It was developed by the Battelle Memorial Institute in conjunction with Caterpillar Incorporated in the USA. The software is centred on a Graphical User Interface that is used to assign welding paths, parameters and material properties to FE models that have been imported from Abaqus/CAE. A closed form analytical thermal solver (CTSP) and advanced user material subroutine (UMAT35) are also included in the package. The final structural analysis of the welded component is carried out using Abaqus/Standard. This paper presents the results of an extensive evaluation of the VFT software package conducted by Rolls-Royce Marine. This was carried out in order to ascertain the capabilities of this software and to determine how it improves on the weld modelling methods currently available using Abaqus stand-alone. This evaluation has shown that VFT significantly enhances the ability of Abaqus to model welding procedures while providing significant savings in both the user and computer time required. A large benefit is seen in the further integration of this software into the Abaqus/CAE package. SIMULIA

Overcoming the Barriers
CAE analysts often face the burden of poor quality and over-detailed geometric models in preparing finite element meshing for analysis. However, end users of SpaceClaim Engineer testify that the application is making a valued impact to alleviate these barriers. To surmount those problems, a solution must be able to import an extensive range of CAD model formats found in the industry and also support an intuitive user interface that is easy to learn for non-CAD experts. SpaceClaim boasts a positive record in each case in the opinion of their customers. McCormick Stevenson, an engineering services company, finds that SpaceClaim serves as a great arbiter of geometry and boasts, “anything can be imported.” The broad appeal of SpaceClaim Engineer as a tool for CAE analysts is further touted by Stig Staghøj Knudsen, a naval architect and CFD expert from Ramboll Group A/S in Denmark. For them, SpaceClaim cleans up CAD models in new ways not previously available saving a lot of product development time in the process. CIMData

Simulation of a Vehicle
In this study, carried out by fka, the hood of the VW Golf V is taken as an example to analyze the potential of a hybrid construction of aluminum and steel. Structural stiffness, oil canning and dent resistance behavior are analyzed using Abaqus/Standard. With the objective of reducing the total hood weight, the performance of the hood is compared to reference values of the series production steel hood. The generated finite element model contains all components of the Golf hood, but most important are the outer and the inner panel, which are designed both in steel and aluminum. Three static load cases are defined to analyze the structural stiffness of the different hood versions. The hood is bended in the lateral and transversal stiffness tests and distorted in the torsional stiffness test. The criterion for all structural tests is the elastic deflection due to the applied load. The dent load cases cover the analysis of the elastic and plastic buckling behaviour. Two different tests are executed, the examination of the oil canning and the dent resistance. The indenter for the oil canning test is modeled by several single point loads, which are set up circular (corresponding to the indenter’s diameter) in the area of the test locations. The Riks mode is used in this simulation. The hemispherical indenter for the dent resistance test is modeled as an extra component. Due to that contact definitions are required. The simulated variations show different lightweight potentials. Taking the material costs into account, a first attempt for an improved hood is made. SIMULIA

Sloshing of Cylindrical
Cylindrical tanks are subjected to the seismic loads in certain countries, for example in Japan. The sloshing of these tanks is very important to consider the integrity of the containers. This phenomenon, however, is an interaction of structure and the fluid, namely oil, and is difficult to be analyzed using computer simulation codes. Owing to the FSI capability of Abaqus and Fluent via MpCCI, the phenomenon has been within the range of simulation. Authors tried to analyze the sloshing using the real seismic acceleration at Hachinohe earthquake in Japan and report the result. SIMULIA

Let’s Go Design in 3D
2D drafting methods are not able to relay the quality and quantity of design information because 2D methods will always rely on human interpretation or visualization skills to interact with a 2D design. This is always difficult for non design staff and almost impossible for computer systems to extract this kind of information, because computers do not have the ability to interpret. As a result, many human errors can occur with traditional 2D design methods. In the past problems such as component collisions, incorrect quantities or parts that don't fit, would happen because a designer who works in only 2D is forced to hold much of the information mentally. Reducing human error by using the 3D modeling design methods minimizes the need for re-work because the design quality is greatly improved. Using 3D design modeling greatly improves design quality because it is a more complete process than 2D design. One most important thing about 3d CAD design is that people can have view of the model from all possible dimensions. It is a highly detailed drawing of what your concept will look like as a finished product. Whether you're designing a new innovative product, creating technical manuals, or requesting quotes from suppliers, 3D CAD design is extremely powerful. But when a 3D CAD design is transformed into a physical 3D print or job shops’ product prototypes, there is no substitute for the tactile and visual feedback a physical model provides to all participants in the design process. Mechanical Designers usually share their work space with drafters or other engineering technicians in quiet, well-lighted surroundings separated from production areas. Working from drawings, sketches, planning sheets, and other engineering and shop data, tool designers must visualize the Design, do the panning, document and verify every step of the way. Because of reductions in defense spending, jobs for mechanical engineering type work will decrease; however, the employment of mechanical engineers is expected to grow about as fast as the average for all occupations through this year due to the demand for new and more complex industrial machinery and tools resulting from the development of more sophisticated automated production processes. The use of 3D modeling technology is essential when you want to develop a superior product. Such a product will not be influenced by human interpretation. Furthermore, it will look like the final model. SolidMasters

Improvements In Fea Of
Finite element analysis (FEA) of a composite overwrapped pressure vessel (COPV) has traditionally been a tedious and time consuming task. FEA is often omitted in the development of many vessels in favor of a “build and burst” philosophy based only on preliminary design with netting analysis. This is particularly true for small vessels or vessels that are not weight critical. The primary difficulty in FEA of a COPV is the creation of the model geometry on the sub-ply level. This paper discusses employing a commercially available tool to drastically reduce the time required to build a COPV FEA model. This method produces higher fidelity models in only slightly more time. Analysis results are presented along with comparisons to burst test data. Additionally the application that inspired this tool’s development is discussed. SIMULIA
Coupled Fluid / Structure
For a system which involves a fluid medium contained inside a deformable structure, such as a fuel tank system, a simulation which couples the structure and fluid may be required depending on the system performance metric of interest. Simulation methods for fluid / structure interaction (FSI) have been gradually developed by CAE engineers since the advent of increased computing power. A limitation in using previous FSI simulations is the dynamic event time period that the FSI method can simulate. With the new CEL function, Abaqus can simulate a coupled fluid / structure dynamic event of several seconds real-time duration in days instead of weeks as compared to other available software. Abaqus/Standard and Abaqus/Explicit CEL function can be used to create a seamless fuel tank system simulation method to assess the fuel tank assembly and road loading performance. SIMULIA
Fatigue Life Estimation
Random response analysis is a linear approach, while most real life random vibrations involve nonlinear components. It is challenge to analyze a nonlinear system subjected to random vibration. This paper presents an Abaqus FEA approach on the fatigue life calculation of an automobile assembly with rubber isolators subjected to random vibration. Random loading is categorized using Power Spectral Density (PSD). An equivalent dynamic analysis or a random response analysis was used to obtain the maximum stress level and location from random vibration. A MATLAB routine was used to post process Abaqus PSD response to calculate the stress cycles/peaks and the fatigue damages were estimated. Hyperelastic behavior of the rubber isolator was derived from Abaqus materials module and the corresponding tests. Random vibration test results with the same PSD input were used to tune and verify the FEA model. SIMULIA
Isight-Abaqus Optimization
Electric Boat’s design process involves evaluating the structural stability of ring-stiffened cylinder structures through finite element analyses to simulate a static pressure load. Each design revision of the cylinders must be evaluated to verify that the structure meets the required stress criteria for the static pressure load; any revision to geometry or material would require the design to be reevaluated. Additionally, it is critical that the weight of the structure is kept as light as possible while still satisfying all stress and deflection criteria. This presentation documents the use of Isight and Abaqus to perform a weight optimization for static pressure loading on a ring-stiffened cylinder, varying geometry and model thicknesses. The use of Isight to run the analysis allows Electric Boat to find an optimized design earlier in the design process. SIMULIA

Nonlinear Dynamic Earthquake
Due to the limitation of computer capacity and the soften of the material constitution, the nonlinear dynamic earthquake analyses of skyscrapers are not practical in engineer’s desktop, and even in the research area they are still open problems. Utilizing ABAQUS’s unique combination of implicit and explicit technologies and capable of solving large problem efficiently, the author solves the problem elegantly and practically. In the analysis model, all members and shear-walls are modeled by plastic zone model, and large deflection effects are taking into account. Especially, as the shear-walls are divided into element size around 0.7x0.7m, the material and geometry nonlinear buckling behaviors of the shear-walls are modeled almost numerical exact. The main analysis procedures and some key parameters are outlined. The analysis results of some prominent projects in China, such as Shanghai World Financial Center(492m in height), Jinta ( 330m in height) and Guangzhou West Tower(435m in height), are also presented. The analysis results are of great help for the design engineers to study the skyscrapers earthquake performance and therefore design the skyscrapers structure more safety and economically. SIMULIA

Taking the High Road:
There is a wealth of evidence that manufacturing jobs are good jobs.1 But not all mamanufacturing jobs are created equal. Published data highlight the considerable variation in pay and productivity across manufacturing industries. For example, workers in the computer and electronic product manufacturing industry earn an average of $34 per hour (as of May 2015), while those in apparel manufacturing earn an average of $17 per hour. Now, thanks to a special tabulation of data from the 2011 Annual Survey of Manufactures (ASM) by the Census Bureau, we can also begin examining differences in the highest- and lowest-paying establishments within the same industry.2 Our special tabulation of ASM data divides manufacturing establishments in two ways. Industries are first categorized at a detailed level (using 4-digit NAICS codes), and then they are divided into four equally sized groups (or quartiles) by payroll per employee.3 The resulting tabulations show payroll per employee, value-added per employee and other output and cost measures for each of the quartiles. This division allows us to see how much wage variation there is between the top- and lowest-paying establishments. The payroll data tells us how much, on average, an establishment is paying all of its employees (including line workers, engineers, and administrators). The variation in pay across manufacturing establishments is quite high. Across all of manufacturing, the lowest-paying establishments are in the bottom quartile of cut-and-sew apparel manufacturing (NAICS 3152), with an average annual payroll per employee of $15,972. At the opposite end of the spectrum is the top quartile of communications equipment manufacturing (NAICS 3342), with an average annual payroll of $113,070—a variation of over 600 percent. As a point of comparison, average payrolls in communications equipment manufacturing are $97,765, or just 170 percent higher than the overall average for cut-and-sew apparel ($36,085).

Coupled Euler Lagrangian
Bird impact damage in complex aircraft structure has been investigated using explicit transient dynamic analysis by Abaqus/Explicit in order to fully employ its large library of elements, material models and the ability of implementing user defined materials. The numerical procedure has been applied on the very detailed large airplane secondary structure consisting of sandwich, composite and metallic structural items that have been modeled with 3D, shell and continuum shell elements, coupled with appropriate kinematic constraints. Bird has been modeled using Coupled Euler Lagrangian approach, in order to avoid the numerical difficulties connected with the mesh. The impact has been applied in the area that is the most probably subjected to the impact damage during the exploitation. The application point and velocity vector have been varied and the comparisons between total, kinetic, internal and damage energies have been performed. Various failure modes, such as CFRP face layer rupture, failure of composite matrix, damage initiation / evolution in the Nomex core and elastoplastic failure of a metallic structure have been investigated. Besides, general contact has been applied as to efficiently capture the contact between impactor and structure, as well as large deformations of the different structural components. Visualization of failure modes has been performed and damaged area compared to the available references. Compared to the classic Lagrangian modeling of the bird, the analysis has proven to be more stable, and the results, such as and damage areas, physically more realistic. SIMULIA
A unified framework is presented that enables coupled multiscale analysis of composite structures and associated graphical pre and post processing within the Abaqus/CAE environment. The recently developed, free, Finite Element Analysis - Micromechanics Analysis Code (FEAMAC) software couples NASA's Micromechanics Analysis Code with Generalized Method of Cells (MAC/GMC) with Abaqus/Standard and /Explicit to perform micromechanics based FEA such that the nonlinear composite material response at each integration point is modeled at each increment by MAC/GMC. The Graphical User Interfaces (FEAMAC-Pre and FEAMAC-Post), developed through collaboration between SIMULIA Erie and NASA Glenn Research Center, enable users to employ a new FEAMAC module within Abaqus/CAE that provides access to the composite microscale. FEAMAC-Pre is used to define and store constituent material properties, set up and store composite repeating unit cells, and assign composite materials as sections with all data being stored within the CAE database. Likewise FEAMAC-Post enables multiscale field quantity visualization (contour plots, X-Y plots), with point and click access to the microscale (i.e., fiber and matrix fields). SIMULIA
Axisymmetric analysis
Typically thermo-mechanical analysis including complexities such as contacts and bolt preloads are carried out using three dimensional models. These analyses require significant time and effort in FE model building, analysis setup, solution, and results processing. It also requires special effort to ensure it is error free. In order to get stable and accurate results element size and time step selection is very important in transient analysis. These aspects are discussed in this paper. This paper also talks about simplified yet almost equally accurate modeling and analysis method for thermo-mechanical analysis using brake fade test simulation as an example. This methodology is based on use of Abaqus/Standard Axisymmetric analysis technique modified to represent effect of discrete bolting, bolt preloads, and contacts within various components of the assembly. Analysis results as well as analysis turnaround times are compared between this new method and the conventional method. Up to 80% time can be saved with significant improvement in the accuracy of the results. SIMULIA
On Nonlinear Buckling
Nonlinear analysis using Riks method is suitable for predicting buckling, post-buckling, or collapse of certain types of structures, materials, or loading conditions, where linear or eigenvalue method will become inadequate or incapable, especially when nonlinear material, such as plasticity, is present, or post-buckling behavior is of interest. These structures usually undergo finite deformations due to complicated loadings or material plasticity before buckling actually occurs, which changes system matrices, and thus, makes the eigenvalue analysis inaccurate, difficult, or even impossible to perform. This study intends to demonstrate the use of Riks method in the nonlinear analysis of buckling and post-buckling behaviors of a flexible structure under bending and compressive loads. The null-point on load-displacement curve is used as criteria for the onsite of instability. The predicted results from finite element analysis compare well with testing data. SIMULIA
Seismic Response of Floating
Seismic response of liquid storage tank floating roofs involve phenomena that require dynamic nonlinear geometric and material behavior as well as surface to surface contact. Good engineering practice requires a practical analytical approach that captures the essential ingredients of structural behavior under earthquake excitation by making reasonable, conservative, and manageable approximations to the actual conditions. This paper discusses an approach used in Abaqus to calculate the stresses and deformations of a liquid storage tank floating roof under seismic loading. It represents a novel application of contact theory to achieve a solution to this problem. The method is validated by a fully coupled fluid-structure interaction (FSI) finite element analysis using actual earthquake ground accelerations. The method is supported by both the American Petroleum Institute (API) and the Petroleum Association of Japan (PAJ). SIMULIA

Highly reliable products require longer test times to verify, and usually takes a few iteration of design-test-fix cycle. Development time can be minimized by (1) doing accelerated testing (ALT) and (2) reducing the design-test-fix cycle by developing methods to predict and test for reliability in simulation environment. Finite element modeling and analysis provides an excellent alternative in evaluating designs to improve on reliability. In this paper, a probabilistic simulation methodology is proposed using a combination of simulation modeling and statistical techniques to predict and improve the drop reliability of a product under repeated random loading. Two examples are illustrated involving two failure modes in two different products a screw pull out and a magnesium housing cracking. Explicit dynamic finite element phone drop simulations were performed in Abaqus to predict the forces in the screw and the principal tensile stress on the housing for various simulation parameters. DOE and Response surface modeling was used to develop regression equations for stress as a function of drop angle. Using the statistical techniques, a probabilistic model was developed by combining the RSM model & statistical distribution of drop angle, to estimate the distribution of the stress. In conjunction, strength degradation models were developed to reflect the housing degradation with each impact. Finally, Monte Carlo Simulations are used in conjunction with the stress-strength interference theorem to predict product reliability. In conclusion, a powerful and practical methodology is proposed that integrates the FEA with statistical methods to predict up front, the reliability of a product. SIMULIA

Direct Digital Manufacturing:
14 unique component designs and 32 total components in each new Stratasys Fortus 900mc are being produced via direct digital manufacturing. Many manufacturers build products in the 10s, 100s, or low 1,000s. In these cases, producing parts with injection molding is often not a wise choice due to the high cost of tooling. With an additive fabrication system, manufacturers can eliminate tooling, which can cost tens of thousands of dollars for a single component or hundreds of thousands of dollars or more for a single project.

Development of a Beta
A novel finite element based topology optimization scheme has been developed and implemented through the use of Abaqus user subroutines. The procedure is based on an iterative material redistribution scheme in which the desired material distribution at each iteration is imposed. A family of Beta probability density functions is utilized to provide a gradual transition from an initial unimodal material density distribution to a bimodal distribution of fully dense and essentially void regions. The efficiency and validity of the scheme is demonstrated through a number of 2-D and 3-D test cases for which the optimal topology is known from analytic optimality criteria. These test cases include classical minimum weight Michell structures as well as newly derived optimal topologies for 3-D structures. The described method is the subject of international patent application number PCT/US2006/062302. To visualize the converged finite element results, procedures are developed to convert the final bimodal material distribution data into contour surfaces of constant density. These contours are then saved in a standardized CAD format (STL) that are imported into commercial CAD software. The CAD models are used directly in rapid manufacturing equipment for the production of prototype parts. Physical prototypes of optimized structures have been manufactured using Laser Engineered Net-Shaping™ (LENS®) and Dimension SST 3D-Printing. In addition to the test cases for which optimal topologies are known from analytic optimality criteria, application of the method to the design of an aerospace component will be presented. SIMULIA
The application of ABAQUS
The connected structure refers to the kind of building which is composed of two or more towers connected by the connecting body in a certain height, belonging to the irregular building structure system. According to “Technical Specification for Concrete Structures of Tall Building” (JGJ3-2002), the time-history analysis method should be adopted in the seismic analysis of the connected structure. The structure may have a larger plastic deformation under rare earthquake, so it is difficult to converge when the implicit solution method is used by the conventional finite element software. While the explicit integral technology provided by ABAQUS can solve the nonlinear dynamics problems better, it has a broader application in elastic-plastic dynamic analysis. Taking a specific project as an object, the application of ABAQUS in seismic analysis of connected structures is presented in detail in this paper. SIMULIA
High-performance Abaqus

Lateral Torsional Buckling
There are plans of constructing bridges longer span like Messina strait bridge. This trend causes the necessity of discussing on the problems of instability analysis such as lateraltorsional buckling. However, lateral torsional buckling analysis of long span bridge is not sufficiently taken yet. For that reason, we apply the Abaqus/Standard to solve the high nonlinear problem. The analysis object is Akashi-kaikyo Bridge which is the longest bridge in the world. This paper presents how to analyze the lateral-torsional buckling of long span bridge applying wind load. SIMULIA
Advances in Mining Simulation
Mine scale finite element simulations are now a key design and planning tool for some of the world’s largest and most challenging open pit and deep underground mining projects. Models with more than ten million degrees of freedom are regularly used for forecasting and probabilistic analysis of Life-of-Mine scenarios. These simulations, sometimes analysing decades of the extraction and continuing deformation of complex infrastructure, are run in less than a day on the Abaqus/Explicit parallel solver using 32 CPUs. The speed and benefits of high-similitude analysis has allowed Abaqus simulation to become more commonplace, and in some cases to be considered a requirement for sufficient analysis of high-value mine developments. The next phase of improved simulation for mines will involve the incorporation of more detail and a more accurate representation of the governing physics of continuum-discontinuum problems, to attain improved similitude at all length scales. Two areas where significant improvements are expected in the very short term are in the simulation of the loads in masses of granular materials and in the behavior of elementary volumes of fractured rock.

Engine Downsizing - An
MAHLE Powertrain (MPT) is constantly exploring new ways to improve the efficiency and performance of engines to meet the demanding objectives Automotive OEM’s are faced with today, i.e. to reduce fuel consumption and emissions. MPT’s key expertise lies in the development of high performance engines with low emissions and excellent fuel economy through the optimisation of gas exchange, combustion, friction and durability. This strategy is being demonstrated by the development of MAHLE’s own state of the art threecylinder 1.2-litre downsizing technology demonstrator engine which has been designed, built and tested at Northampton in the UK. One of the objectives of the project was to design a compact engine with high specific power output by using a turbo charger combined with state of the art direct injection technology and variable valve timing. This ensures that vehicle performance targets can be met using the smallest capacity engine thus minimising throttling losses which otherwise leads to high fuel consumption. With such a high specific power output predictive analysis has played a key role in guiding, validating and optimising the design. This paper highlights the use of Abaqus to perform structural analysis of the main engine: connecting rod, crankshaft and cylinder block bottom end as well as thermo-mechanical analyses of the head and block assembly and exhaust manifolds.

Finite Element Modeling
A finite element (FE) model of the human foot and ankle was developed from 3D reconstruction of 2 mm coronal MR images from the right foot of a normal male subject using the segmentation software, Mimics. Solid models of 28 foot bones and encapsulated soft tissue structures models established in Solidworks software were imported into ABAQUS for creating the tetrahedral FE meshes. The plantar fascia and 72 ligaments were defined by connecting the corresponding attachment points on the bones using tension-only truss elements. Contact interactions among the major joints were prescribed to allow relative bone movements. A foot support was used to establish the frictional contact interaction between the foot-support interfaces. The contour of the arch-supporting foot orthoses was obtained from digitization of the subject’s foot via a 3D laser scanner. Algorithms were established in Matlab software to create surface models from the digitized foot surface. Solid model of the foot orthoses established in the Solidworks software was properly partitioned in ABAQUS for creating the hexahedral FE meshes. The encapsulated soft tissue and orthotic material were defined as hyperelastic while other tissues were idealized as homogeneous, isotropic and linearly elastic. The ground reaction and extrinsic muscles forces for simulating the stance phase of gait were applied at the inferior ground support and at their corresponding points of insertion by defining contraction forces via axial connector elements, respectively. The FE predictions are being validated by experimental measurements conducted on cadavers and on the same subject who volunteered for the MR scanning. SIMULIA
Terminator meets Simulator:
When computer generated imagery (CGI) first started to appear on movie and video game screens, the emphasis was to make something look close enough to its real counterpart to satisfy audiences. As graphics and computing capability progressed, audiences became less satisfied with “cartoon-like” animation; they demanded more realistic visuals. The entertainment industry reached across the aisle to the scientific community in attempt to incorporate more physical realism into animations. As a result, today’s physics- based CGI can fool even a scrutinizing scientist into believing what he’s seeing is real. While the entertainment industry profited by collaborating with the scientific community, the benefit is mutual. For example, in order to study the fit performance of a dust mask with facial movement, we borrow a CGI technique to make simulation feasible. Specifically, the complex and intricate movements of the face are represented using a high resolution motion capture technique. Similarity between motion capture and finite element data forms allows their interchangeability. In this study, detailed motion capture data of real facial movement was interpreted to produce a finite element model (node and element definitions) along with a time history of nodal displacements. The finite element data was stored as an Abaqus output database and subsequently used as a global model to drive a similar facial submodel to evaluate the fit and sealing performance of a pouch style face mask design under realistic use conditions. This paper outlines the analysis approach and shows results from the simulation. SIMULIA
Simulation of the Forming
This study concerns simulation of the forming process of a carton-based package for liquid food (for example, milk or juice), and how the packaging material interacts with the fluid during the forming. The carton-based package is formed inside a filling machine while the fluid is being filled into the package. The carton-based package is thin with low bending stiffness and is thus deformed significantly at small loading. This implies that the forming of the package to a large extent depends on the dynamics of the fluid inside the package. In the filling machine, the filling pipe enters the tube where the carton-based web is partly shaped into a longitudinally sealed tube. The package is formed and transversally sealed below the fluid surface. When forming the transversal seal of the package, the cross-section of the tube changes from open circular to closed in a short period of time, which causes considerable pressure waves inside the package. In order to control the pressure waves and thereby the forming of the package, a pressure flange is mounted on the filling pipe inside the carton-based tube. A coupled Eulerian- Lagrangian approach in Abaqus/Explicit is used in order to study both the deformation of the packaging material and the fluid and the interaction between them entirely within a single finite element model.
