Altair SimLab

Altair SimLab is like a smart assistant for engineers who need to run complex simulations without wasting time on tedious setup. It’s a user-friendly tool that helps you go from CAD to results very quickly, automating the tedious tasks like meshing, boundary conditions, and solver setup. Whether you're working on structural, thermal, multiphysics or fluid simulations, SimLab makes the whole process feel smoother and way less frustrating than traditional tools. It’s perfect if you want accurate results but don’t have the patience for a steep learning curve or the high cost of traditional FEA tools.

Electronics Cooling and PCB Simulation

Accurately model complex electronic assemblies and perform thermal/electro-thermal analyses, including chip and package-level detail. Built-In Ball Grid Array (BGA) creation and modification. Import and define multi-layered PCBs with anisotropic thermal properties to capture realistic heat spreading through board stacks. Apply detailed power maps from ECAD tools directly to IC packages and PCBs for more accurate thermal simulations.
