Commentary By Jeffrey Rowe, Editor
We have followed LMS for several years and have been impressed by the breadth, depth, and uniqueness of its product offerings. We also have been awaiting this announcement for some time on the release of LMS Virtual.Lab Rev 9, its simulation environment for functional performance engineering. LMS Virtual.Lab is an integrated software suite that simulates the performance of mechanical systems with regard to attributes such as noise and vibration, durability, ride and handling, and dynamic motion. With Rev 9, LMS Virtual.Lab covers virtually all the critical process steps and required technologies to perform an end-to-end assessment of designs in key disciplines that are
especially important to the automotive and aerospace markets. The LMS Virtual.Lab suite’s modules are based on CAA (Component Application Architecture), the open architecture PLM system from Dassault Systemes.
LMS Virtual.Lab Rev 9 provides a digital engineering process for refining critical functional performance attributes before committing to physical prototyping. For example, LMS Virtual.Lab lets users accurately assess such things as the radiated noise of a new engine design, the vibration handling and associated comfort levels of a complete vehicle, or the fatigue resistance of an aircraft landing gear. Using Virtual.Lab, you can analyze a multitude of design options, and drive major design choices from the perspective of key performance attributes.
Technologies included in Rev 9 accelerate the building and testing of component and system-level virtual models. With the integration of new hybrid simulation capabilities, Virtual.Lab Rev 9 validates virtual models with test data, uses real-world validated loads, and combines test models of existing components with virtual models of new components. These virtual simulation capabilities also make simulation results more accurate.
As it has for some time, Virtual.Lab Rev 9 offers application-specific modules for areas, such as powertrain acoustics, powertrain dynamics, vehicle dynamics, full-vehicle noise, vibration, and harshness (NVH), component and system-level durability.
Some of the modules available with LMS Virtual Lab Rev 9 include:
LMS Virtual.Lab Finite Element Method (FEM) Acoustics
LMS Virtual.Lab FEM Acoustics offers an advanced method for simulating acoustics using FE meshes while still modeling the propagation area. Since these types of models tend to be large, advanced computing techniques and solvers are essential. With LMS Virtual.Lab Rev 9, FEM acoustics provides more solver options and high-tech routing features to solve practically any application regardless of size or frequency range.
LMS Virtual.Lab Boundary Element Method (BEM) Acoustics
Time domain BEM is a new time-based method for acoustic wave propagation applications. Users can see how the acoustic waves spread throughout an acoustic field. FMBEM ATV combines LMS’ patented ATV (Acoustic Transfer Vector) technology with the unique FMBEM (Fast Multipole BEM) solver introduced in LMS Virtual.Lab Rev 8. It is a way to efficiently solve problems such as high-frequency acoustic structural radiation issues.
LMS Virtual.Lab Ray Tracing
This new ray tracing solver is well-suited for interior acoustics applications, such as wall absorption assessment. It is also efficient for high frequency acoustics.
LMS Virtual.Lab Source Identification
Source identification is an inverse acoustic technique that accurately determines vibration sources for a better understanding of noise problems and ultimately better noise and vibration system optimization. By coupling a near-field measurement with Inverse Numerical Acoustics, users can simulate vibration sources to use as loads for accurate forward acoustic predictions (near field measurement applied for far field simulation).
LMS Virtual.Lab Aero-Acoustics
Enhanced for aero-acoustic applications, LMS Virtual.Lab Aero-Acoustics now contains a variety of features to reduce flow-induced noise, including conservative mapping, quadrupoles including truncation, and confined fan.
LMS Virtual.Lab Motion
Beyond improved productivity, LMS Virtual.Lab Motion addresses real-world problems, such as driving dynamics, aerospace, wind, powertrain, tracked vehicle and functional and physical (1D/3D) co-simulation.
LMS Virtual.Lab Durability
This new thermal fatigue methodology analyzes the impact of changing temperatures on fatigue behavior both by modeling the effect of temperature on the fatigue material properties, as well as accounting for the influence of temperature cycles on fatigue performances. This is a good way to accurately evaluate fatigue for engine parts, exhaust systems, turbo chargers, and other parts that are influenced by cyclical temperatures.
For some time, LMS Virtual.Lab has integrated Design of Experiments (DOE), Response Surface Modeling (RSM) and Advanced Optimization techniques. These capabilities let Virtual.Lab users automatically assess several design alternatives, and use design methodologies to assess the influence of real-world variability in a search for safer, higher-quality, and better performing products.
For automotive and aerospace design simulation, the LMS Virtual.Lab suite remains one of the most comprehensive, capable, and versatile packages we have seen.
The Week’s Top 5
At MCADCafé we track many things, including the stories that have attracted the most interest from our subscribers. Below are the five news items that were the most viewed during last week.
Dassault Systemes (DS) announced that the technology for automatic motion and path planning from Kineo Computer Aided Motion (Kineo CAM) has been integrated with 3DVIA Composer. This integration, named 3DVIA Path Planning, allows users to communicate complicated steps of interactive documentation with automatically generated, lifelike animations, rather than photos and text. Assembly and maintenance tasks of tightly fitting components have always been difficult to describe, regardless of the communication tool used. These processes are complex to explain using traditional photo and text instructions, often leading to misinterpretation, reduced quality, or damage to sensitive
components. A potential solution to this challenge is to provide users with 3D interactive and animated instructions, which are more effective in communicating difficult concepts. Creating 3D animations has traditionally been difficult and time consuming. The combination of 3DVIA Composer and 3DVIA Path Planning now automates the animation creation process, increasing the quality and productivity of 3D interactive experience authoring. 3DVIA Composer automates the creation of assembly and disassembly procedures, technical illustrations, interactive 3D product experiences, training materials, marketing materials, and sales tools.

CD-adapco released STAR-CCM+ V4.06, the third major version of their flagship engineering simulation software released during 2009. In the six years since its first release, STAR-CCM+ has evolved into more than just a CFD code, and is now an integrated platform for powerful multi-disciplinary engineering simulation, including: combustion; multiphase flow; heat transfer through solids and fluids; dynamic fluid body interaction; and solid stress: all from within a single environment. Principal new features of STAR-CCM+ V4.06 include models to simulate broadband aeroacoustic noise and aerodynamic flutter, together with a range of customer requested enhancements aimed at increasing both
user productivity and simulation capability. Using multi-physics simulation technology, STAR-CCM+ provides engineers with the means to predict the occurrence potentially harmful physical phenomena, providing detailed engineering data that can be used to modify designs in order mitigate their impact. Building on existing aeroacoustic capability, the latest release of STAR-CCM+ provides new tools that enable engineers to quickly and easily identify the location and strength of flow generated broadband noise sources. In addition to direct methods using LES and DDES, STAR-CCM+ 4.06 introduces broadband aeroacoustic prediction using the Lilley source term as well as four different models:
Proudman, Linearized Euler, Goldstein, and Curle. Beyond the prediction of aeroacoustic effects, an extension to the Harmonic Balance capability provides tools for the analysis of blade flutter in rotating machinery, with computational time scales that are drastically reduced compared to traditional transient methodologies.
MecSoft Corp., the developer of VisualMILL, RhinoCAM, VisualMILL for SolidWorks and other CAM software, has announced the availability of a 64-bit version of VisualMILL for SolidWorks, an affordable integrated CAM software solution for SolidWorks users starting at $999 (US).The 64-bit version of the software will be available free of cost to existing 32-bit customers.64-bit products running on 64-bit Windows operating systems can handle large amounts of memory, (4GB or more RAM) more efficiently than a 32-bit operating system. More available memory can result in greater efficiency and better overall system performance when running memory intensive applications such as SolidWorks and
VisualMILL for SolidWorks. This is a result of reduced disk paging and memory thrashing that is typical of 32-bit systems running such memory intensive applications due to the inherent 2GB address space limit of these systems.
