New Functionality

  • The Reaction Engineering Module is fully integrated into COMSOL Multiphysics. This means that you can couple reaction models to model systems of reactors that are 0D combined with 1D, 2D, and 3D models directly in the same user interface.
  • The CAPE-OPEN Thermo Socket is available in the user interface. The socket allows you to simultaneously run calculations in COMSOL and in your favorite package for thermodynamic and physical properties of fluids. You can set up this socket directly in the Model Builder. All major packages for calculation of thermodynamic and physical properties of fluids are CAPE-OPEN compliant.
  • An interface for surface reactions simplifies the definition of these reactions, especially when these are coupled to homogeneous reactions.

Backward Compatibility

All backward compatibility issues are planned to be solved for version 4.0a unless explicitly stated.

Export from Reaction Engineering Lab to COMSOL Multiphysics does not include material balances where equilibrium is used to eliminate the reaction kinetics.

You can treat such systems by using large values for the rate constants and keeping the relation between the forward and reverse rate constants so they satisfy the equilibrium relation within a given accuracy. The re-implementation of this export functionality is planned for version 4.1.
