Simulation and Analysis

Data Visualization for Optimization and Lightweighting

The use of simulation in engineering is shifting from sequential (one at a time) to parallel (many at a time, running simultaneously on high-performance computing systems). The move is precipitated largely by optimization and lightweighting, which require evaluating a series of design options or families of designs to identify the best candidates.

But this adds a new dimension to simulation. Now, you need a way to view the results — the best ones, as identified by the software’s algorithm — in a comprehensible fashion to understand the correlations between different parameters and the geometry. For example, what happens to the aerodynamic performances of the vehicle when you increase the curvature of the hood by a certain degree? Or how does the position of the side mirrors affect the car’s drag? →']);" class="more-link">Continue reading

MSC Software Launches Roadshow to Explain Material Simulation

MSC Software, well-known as the developer behind MSC Nastran, is launching a roadshow this year to discuss the importance of advanced materials. Between Sep. 3 to Oct. 9, MSC plans to host talks and discussions in five different cities:

  • Wednesday, September 3rd, 2014 – Newport Beach, CA
  • Wednesday, September 24th, 2014 – Wichita, KS
  • Thursday, September 25th, 2014 – Dallas, TX
  • Wednesday, October 8th, 2014 – Huntsville, AL
  • Thursday, October 9th, 2014 – Seattle, WA

Intel Releases Xeon E5-2600/1600 v3 Lineup, Targetting Data Centers and Virtualization

A week ago, Diane Bryant, senior VP and general manager, Intel Data Center Group, introduced the new processor lineup — E5 2600/1600 v3 series — at an event at the Terra Gallery in San Francisco, California. The processors, Intel says in its press release, are “central to enabling a software defined infrastructure,” what Intel calls “the foundation for cloud computing.”

Intel writes, “With up to 18 cores per socket and 45MB of last-level cache, the Intel Xeon E5-2600 v3 product family provides up to 50% more cores and cache compared to the previous generation processors.”

In a presentation showcasing possible applications, Intel offers statistics showing that the E5-2600/1600 v3 processors give significantly better performance over their predecessors. LS-DYNA simulation software, for instance, shows up to 50% faster on E5-2697 v3 compared to E5-2697 v2. Furthermore, MSC Nastran Software shows up to 46% faster, and ANSYS Mechanical up to 38% faster on v3 compared to v2. →']);" class="more-link">Continue reading

Transport Vehicle Goes On An Aluminum Diet

It only stands to reason that an aluminum smelter in need of utility vehicles for operations and maintenance would want those vehicles to be made out the same aluminum it manufacturers, not steel.

Manufacturing a structurally-sound utility transport out of a wholly new material wasn’t the only design challenge for this effort, put into play by Aluminerie Alouette, a Canadian aluminum smelter. The new design also had to accommodate an electric power train—a requirement because the smelting process creates such a strong static magnetic field that regular internal combustion engines have a hard time operating properly within that environment. The third requirement was to create a vehicle design that would allow for easy recycling at the end of the transport’s lifecycle. ']);" class="more-link">Continue reading

JLR’s Holistic Light Weighting Approach Nets Award

Jaguar Land Rover (JLR) put its luxury Range Rover sports utility on a diet. The effects were so impressive that the auto OEM took home the 2014 Enlighten Award, an accolade bestowed by simulation software provider Altair in collaboration with the Center for Automotive Research (CAR).

The Altair Enlighten Award, the automotive industry’s first award program that acknowledges innovations in vehicle light weighting, was handed to JLR in acknowledgement of its accomplishments in the lightweight architecture design of the newest Range Rover vehicle. Thanks to JLR’s holistic approach to CO2 reduction, the new Range Rover body achieved a 40% weight savings, weighing in at 658 pounds compared to its previous body weight of 1,096 pounds.

What’s distinct about JLR’s light weighting efforts is that it pursued a holistic approach throughout the entire vehicle development process, according to Dave Mason, senior vice president, Global Automotive for Altair. Specifically, JLR linked its strategy of weight reduction in the body and chassis systems to powertrain and related secondary weight savings, while at the same time, maximizing its use of recycled materials and lowering energy consumption during the manufacturing stage. →']);" class="more-link">Continue reading
