Cut costs with CAE simulations

Computer Aided Engineering

Engineering Confidence through Simulation

In CAE, we create precise finite element models, analyze them for different load situations and study physical responses such as displacement, strain and stresses. The aim is to design products that perform better in the real world.

Safer designs, lower costs and shorter development cycles are familiar challenges for manufacturing industries. In automotive sector, vehicle crashworthiness is a demanding regulatory requirement.

To satisfy regulatory requirements and address consumer safety concerns, leaders in the automotive market are seeking new technologies that can help them develop improved crashworthiness and occupant protection, while containing costs and accelerating time-to-market.

Our core strength is modeling and CAE simulation of automotive BIWs, engine and transmission components, seating systems, trim parts, instrument panels, consoles and closure components like doors, hood and tailgate.
