ICAT is one of the leading centres for testing, R&D, design, development and validation in support of a Government of India funded initiative to develop facilities for automotive testing & development. To meet the challenges of the automotive industry, they need to employ optimization to decrease vehicle weight while maintaining proper strength. For a major challenge for the rollover testing for bus industry, they used Altair Radioss for roll over simulation and Altair OptiStruct for optimization leading to shortened development time for their customers by over 50%.
