HEAT

Built on the finite element method, HEAT provides designers with comprehensive thermal modeling capabilities. The finite-element heat transfer and Joule heating solver easily handles conductive, convective, and radiative effects, as well as optically and electrically generated heat, enabling engineers to have confidence in the stability and reliability of their designs.

Key Applications
