The Heat Transfer Module provides a combination of simulation capabilities to model heat transfer via conduction, convection, and radiation, as well as the ability to couple these to other physics. With boundary conditions for describing convective and radiative effects, contact resistance, as well as thin highly-conductive shells, you can simulate anything from a simple "back of the envelope" model to a full model with all effects explicitly described.

The COMSOL Reaction Engineering Lab uses reaction formulas to create models of reacting systems. It solves the material and energy balances for such systems, including reaction kinetics, where the composition and temperature vary only with time.
The Structural Mechanics Module is dedicated to the analysis of components and subsystems where it is necessary to evaluate deformations under loads. It also contains special physics interfaces for the modeling of shells, beams and trusses.
Getting your CAD geometries ready for FEA modeling is easier than ever with the CAD Import Module. It facilitates the reading of industry-standard formats such as STEP, IGES, ACIS® (SAT®) or Parasolid®. Extra add-ons support file formats for packages that have their own geometry kernel.
