Analysis and Simulation
Simulation is a vital tool in understanding existing designs and for developing new ones. It’s much more than auto-meshing CAD and making “pretty pictures”, it’s all about finding out what is really going on in a system.
TSI offers a broad range of analysis and simulation services to industries including automotive, aerospace, consumer product, industrial equipment, biomedical and general structures.
TSI’s in-house simulation tools include Atair HyperWorks and LSTC LS-Dyna; both are world-leading analysis codes. We provide simulation training and mentoring services and are also a sales agent for the Altair product suite.
