Coupling to Other Physics Interfaces
The COMSOL Multiphysics software is not limited to the aforementioned multiphysics couplings — there are many other phenomena that can be easily modeled another physics interface (for example, in the Model Inputs section of a Fluid Properties node). Additionally, COMSOL Multiphysics includes powerful coupling operators that enable physics interfaces to be linked by projections, extrusions, or scalar quantities such as integrals and global averages.in polymer flows. In many cases, physics interfaces can be coupled simply by entering expressions from one physics interface (such as the local temperature) into fields in

Other types of fluid flow, such as turbulent flow and dispersed multiphase flow, can be found in the CFD Module. More extensive descriptions of heat transfer, such as in turbulent flow or involving radiation, can be found in the Heat Transfer Module. Furthermore, some applications involving the flow of liquids and gases in porous media are better handled by the Chemical Reaction Engineering Module.
