SimLab is a process-oriented multidisciplinary simulation environment to accurately analyze the performance of complex assemblies.

Multiple physics including structural, thermal and fluid dynamics can be easily setup using highly automated modeling tasks, helping to drastically reduce the time spent creating finite element models and interpreting results. Altair’s robust, accurate and scalable solvers can run either locally, on remote servers or in the cloud.

An intuitive and self-explanatory graphical user interface covers all aspects of the modeling process. Instead of tedious geometry clean-up, work is performed directly on the geometry – imported and updated via the bi-directional CAD coupling - by defining mesh specifications for individual regions.
