Additive manufacturing (AM) technology enables the possibility of realizing highly efficient, optimized structural components with configurations not achievable using conventional manufacturing methods. The Altair and Solid Thinking toolsets provide advanced capabilities to design structural topologies to minimize weight and maximize other performance criteria.

Seat Design for Crash in the Cloud - NAFEMS World Congress 2015

The benefit of design exploration and optimization is understood and accepted by engineers but the required intensive computational resources have been a challenge for their adoption into the design process. The HyperWorks Unlimited (HWUL) appliance provides an effective solution to these challenges as it seamlessly connects all the necessary tools together in the cloud. The aim of this study is to showcase the benefits of HWUL on an optimization driven design of a complex system. For this purpose an automotive seat design for crash loadcases is selected.

Improving Rudder Shock Loading Following a Nearby Blast Event Using RADIOSS

Engineers in the Marine, Shipbuilding, and Offshore industries face many design challenges including physical space constraints, extreme weather conditions, deep water and remote locations. These constraints create an extreme environment for the engineer to develop a sound, reliable and safe operating platform.

HyperWorks 14.0 Webinar: Structural Analysis & Optimization

HyperWorks 14.0 introduces expanded optimization, NVH, and nonlinear solver capabilities, helping to get to the right design with a simulation-driven process. Providing fast, accurate solutions, OptiStruct’s capabilities have been elevated to include more nonlinear analyses, as well as the implementation of new contact algorithms, improvement in solution speed and enhancements in thermal contact. OptiStruct parallelism has been further developed, with normal modes and frequency response analysis made faster. Optimization enhancements include a new alternate optimization algorithm in OptiStruct as well as implementation of a first-to-market solution for the design and optimization of lattice structures. 3D topology optimization for RADIOSS nonlinear analysis has been added.

Bremar Automotion uses Altair RADIOSS to Design & Certify FIA Motorsport Roll Cages

“The Altair product is it for us in terms of simulation. That’s all we use. It’s great to be able to show such good correlation between the simulations and physical testing, and to have confidence in not only our approach, but also the Altair product as well. It’s a great product for us to be using, and the test results and these images just back that up for us.” Brett Longhurst, Managing Director, Bremar Automotion

Getting it right the First Time; how FE-Simulation with RADIOSS supports Sigma Connectivity in Streamlining the Development Process

Simulation is extensively used in the early development phases at the Sigma Group, where about 10-15 engineers are working with different types of simulations.

Using HyperWorks to Develop Human Body Models for Vehicle Crash Simulation

Wake Forest Baptist Medical Center is a leading research university in biomedical sciences and bioengineering that provides students and faculty with outstanding opportunities for personal and professional growth.

Digimat and RADIOSS for UD Material Modeling with Anisotropic Progressive Failure

The prediction of CFRP materials in the automotive industry requires simulation of the failure through an anisotropic progressive failure model, provided by Digimat.

Using RADIOSS to Reduce the Simulation Time Without Compromising on the Accuracy

In this 45 minute webinar, you will learn: How RADIOSS can use a time step higher than the theoretical one while still respecting the stability condition. How advanced mass scaling (AMS) can be used on complex RADIOSS explicit models. The method dramatically reduces the elapsed time, without modifying the mass of the model or the rigid body translations, therefore providing very accurate results. Examples will we provided to illustrate how the method can be applied on large-scale FEA models. <br/><br/> <i>This is a recording of the webinar that took place on September 12, 2012 </i>
