Problems involving any combination of conduction, convection, and radiation are solved easily with the Heat Transfer Module. It finds extensive use in systems that involve the generation and flow of heat in any form.

A variety of specialized modelling interfaces are available for different formulations and applications such as surface-to-surface radiation, non-isothermal flow, heat transfer in structures made of thin layers and shells, and heat transfer in biological tissue.

The Heat Transfer Module allows for arbitrary couplings to other application modes in Comsol Multiphysics and its modules for Multiphysics modelling. This is particularly relevant to applications such as thermal management in the electronics industry, thermal processing and manufacturing, and medical technology and bioengineering.
