Accelerating with Shafts, Gears, and Cams The parametric design capabilities of Autodesk® Inventor® not only provide stunning visualizations, but they make it possible to truly realize a product, long before it is physically produced. The resulting shorter time-to-market, and increased profitability, have led designers in a variety of industries to choose Inventor’s powerful 3D digital prototyping. They have benefited from hundreds of features that save hours, days, or even weeks of design time. In addition to these now expected benefits of digital prototyping, Autodesk Inventor goes a step further with its accelerators. 0
Adaptive T-spline Surface Fitting to Z-Map Models Surface fitting refers to the process of constructing a smooth representation for an object surface from a fairly large number of measured 3D data points 30
Complexity v's Manufacturability - Plastic product design principles The rapid development of modern 3D CAD systems have enabled the evolution of product design, and as a result, a move to more organic forms and ever increasing geometry complexity. Just think about the change in design from the conventional box shaped vacuum cleaner to the modern Dyson. This paper focuses on design fundamentals and the impact they have on the manufacturing and production processes. 6
CONVERSION BETWEEN T-SPLINES AND HIERARCHICAL B-SPLINES T-splines is a recently developed surface modelling technique which is a generalization of B-splines and allows true local refinement. 73
Developing Sustainable Designs for Enduring Value Developing Sustainable Designs for Enduring Value - White Paper developed by White Paper focuses on using a multi-faceted approach to developing designs with examples using SolidWorks CAD. Authored by the Technical Team at EGS India - SolidWorks Reseller Chennai, Coimbatore, Trichy, Tamil Nadu, India 2
Drift Model for Two-Component Flows In fluids composed of multiple components, e.g., fluid/particles, fluid/bubbles, fluid/fluid mixtures, where the components have different densities, it is observed that the components can assume different flow velocities. Velocity differences arise because the density differences result in non-uniform body forces. Often the differences in velocities can be very pronounced, for example, large raindrops falling through air or gravel sinking in water. Under many conditions, however, the relative velocities are small enough to be described as a “drift” of one component through the other. Examples are dust in air and silt in water. This paper discusses how the drift model in FLOW-3D simulates these processes. 3
Implicit Advection in FLOW-3D® : Its Uses and Limitations A powerful implicit advection technique has been incorporated into FLOW-3D®, Version 9.2. This paper illustrates uses of this technique to show its advantages, but also indicates certain limitations related to the accuracy of implicit methods. 30
Improvement on the Dimensions of Spline Spaces A T-mesh is basically a rectangular grid that allows T-junctions arising from T-spline ([3], [4]). T-meshes are formed by a set of horizontal line segments and a set of vertical line segments. 26
Introduction to SinapsPlus® SinapsPlus® (pronounced “synapse plus”) is a complete graphical user interface and model debugging environment for the SINDA/FLUINT thermal/fluid simulation package. SINDA/FLUINT is a comprehensive software package used by over 400 sites in the aerospace, energy, electronic, automotive, aircraft, HVAC, and petrochemical industries for design and simulation of heat transfer and fluid flow problems. 9
Introduction to SINDA SINDA/FLUINT is a comprehensive software package used by over 400 sites in the aerospace, energy, electronics, automotive, aircraft, HVAC, and petrochemical industries for design, simulation, and optimization of systems involving heat transfer and fluid flow. It is the NASA-standard analyzer for thermal control systems. 24
Parallel Processing in PowerMILL 10 This paper aims to remove the marketing hype surrounding parallel processing and its performance impact on CAM systems. Delcam’s research to date helps to separate the fact from the fiction and gives you a true understanding of parallel processing in the CAM environment. In particular, this paper addresses the following questions: • What is parallel computing? • What influence does hardware configuration have on toolpath calculation times? • How does parallel computing really benefit end users? • How will Delcam continue to harness the power of the latest multi-core processors to benefit all aspects of CAM programming? 1
Technical Requirements of Smart Engineering Simulation Apps Democratization of numerical simulation through the development and deployment of Smart Engineering Simulation Apps is gaining momentum; however such apps must satisfy several important technical requirements to ensure the level of reliability needed for professional use by experts and no-experts alike. 0
Virtual Classroom Brings CAD/CAM Training Straight to Your Desk Training is critical to getting the most out of any CAD/CAM system. However, it is often a challenge to deliver training in the most timely and effective manner. Any busy shop manager can tell you that there is precious little time to sit down with a training manual and struggle to learn the software on your own or, worse, send an important team member out for a week of classroom training. 38
