Mentor Graphics couples its tools for component and system-level CFD CFD was once the exclusive realm of analysts with deep theoretical backgrounds and extensive experience. While those analysts still rule the realm, they’re no longer alone. The growth of early (often called “upfront” or “concurrent”) CFD tools has opened the field up to a new…

by Evan Yares, Senior Editor & Analyst, Software It’s more about domain knowledge than software ease of use A shift in CAE software started, quite a long time ago, when SolidWorks started including a basic version of Cosmos FEA with their eponymous CAD package. It was the beginning of the “red is bad, green is…

Multiphysics has earned the reputation as an excellent approach for simulation in engineering and science. Applying multiphysics simulation early in the product development process brings you reliable computer models to verify and optimize your designs This webinar will demonstrate how the COMSOL LiveLink for SolidWorks bridges the gap between design and analysis, integrating real-world simulation…

Finite Element Analysis has been around for a long time. Better than 50 years. Though it took awhile for computers to catch up with the processing and memory demands of FEA, today’s average PC is up to the task, even for challenging problems. Why, then, is FEA still thought of by many engineers as a…

If you were going to pick a challenging use case for CFD software, you couldn’t do much better than Formula 1 racing. It’s a high-stakes game, with fast development cycles, and even faster feedback on failures. Every two weeks during the season, F1 teams get a reality check on their engineering. As a practical matter,…

This webinar introduces new techniques and case studies for efficiently increasing the fidelity of system models for multibody robotic system design. Using symbolic computation techniques, multibody models can be effectively preprocessed to select optimal coordinate frames, eliminate redundant calculations, simplify algebraic constraints, and generate computationally minimal code for real-time deployment. Furthermore, novel mathematical techniques can…

The viscosity of blood is widely regarded as an indicator of general health. When a blood vessel is damaged or broken, blood loss needs to be minimized, so a series of reactions begins to form a blood clot. A number of medical conditions adversely affect this process and in these cases patients are often prescribed…

NASA’s Jet Propulsion Laboratory is implementing Maple, MapleSim, and MapleNet software in its various space-related projects. Whether creating America’s first satellite, Explorer 1, sending the first robotic craft to the moon, or exploring the edges of the solar system, JPL has been at the forefront of pushing the limits of exploration. Curiosity, JPLs latest space…

Arktos Developments Ltd. (ADL), designer and manufacturer of an amphibious vehicle known as the Arktos Craft, uses Autodesk’s simulation software to prepare its products to operate in some of the world’s most environmentally demanding locations. Originally designed as an amphibious evacuation craft for Arctic offshore oil facilities, the Arktos Craft can move from -50° C…

Until recently, most finite element analysis (FEA) applications undertaken by design engineers were limited to linear analysis which provides an acceptable approximation of real-life characteristics for most problems. However, occasionally more challenging problems arise that call for a nonlinear approach. In this webinar, you will hear about real-world nonlinear applications and case studies associated with…

By David A. Hall, Senior Product Manager, National Instruments and Sherry Hess, AWR, A National Instruments Co. Reprint Info >> Test instrumentation is fundamentally changing—the lines between electronic design automation software and test bench software are blurring. The result is a faster design process. The concept of combining simulation software and measurement hardware in the…

Much like a human arm with interconnected bones, muscles, and tendons, earth moving equipment components must harness a complex array of parts to perform in perfect synchrony. Key to an earth mover’s fluid movements is an array of hydraulic cylinders, located along the boom, arm and bucket, that act as actuators to convert hydraulic energy…

By Edited by: Laura Carrabine, Senior Editor NASA uses an innovative and cost-effective unmanned aircraft to gather earth science data around the world. It was designed by the U.S. Naval Research Laboratory and developed at NASA’s Ames Research Center. The Systems Integration Evaluation Remote Research Aircraft (SIERRA) is routinely deployed for environmental collection missions over…

Reprint Info >> Here are a few reasons why combining parametric and direct CAD offer benefits to you, your team, and the products you create. There are a few differences between parametric and direct modeling. The parametric paradigm provides an “engineer it” approach to design which requires you to anticipate and define feature constraints, relations,…

By Scott Bradley, Design Modeling, and Simulation Lead System Design, Evaluation Ltd. Hertfordshire, UK In the design of almost any new high explosive ammunition, the most complex and often problematic component is the fusing system. The fuse must incorporate a Safe and Arm device to ensure that the projectile may only enter the armed state…

At the seventh annual user conference in October 2011, Comsol launched its latest version of its flagship product Comsol Multiphysics 4.2a. It includes the Particle Tracing module and Livelink for Creo and many new features. Particle Tracing computes the trajectory of particles in a fluid or electromagnetic field, including particle-field interactions. Applications include flow visualization,…

By Andras Poppe, Mentor Graphics, Mechanical Analysis MicReD, Budapest, Hungary Amid all the promotion of solid-state superlatives – from data rate to feature size to LED light output – junction temperature is rarely discussed. That is because junction temperature (TJ) is an undesired but unavoidable side effect of high currents and switching speeds. A p-n…

When it comes to training soldiers and Marines to operate ground vehicles, Moog’s technology ensures a driver simulator feels every bit as true and tactile as the real thing. Moog is supplying and supporting the high-performance electric motion systems that underpin FAAC Incorporated’s latest-generation driver simulators. These simulators include the MATV and MRAP Cougar vehicles.…

By Lateef Uddin, Product Engineer, Drives and Motion Division of Yaskawa America, Waukegan, Ill A key goal in our product development process is to use design and analysis tools to reduce the number of prototypes we must build and test during the concept design phase.

Man-made satellites have to fit into a compact package. Briefly protected inside a rocket while blasted through the atmosphere, a satellite is launched into orbit to continue its unmanned mission alone. It uses gyroscopes, altitude thrusters, and magnets to regulate sun exposure and stay pointed in the right direction. Once stable, the satellite depends on…
