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.

HEAT is a solver within Lumerical’s DEVICE Multiphysics Simulation Suite, the world’s first multiphysics suite purpose-built for photonics designers. The DEVICE suite enables designers to accurately model components where the complex interaction of optical, electronic, and thermal phenomena is critical to performance. As part of Finite Element IDE, designers can quickly analyze complex active devices while benefiting from Lumerical’s industry-leading usability, performance, and accuracy.
