Ready-made interfaces make it easy to model single and coupled processes related to subsurface flow. The module is well suited for studies such as oil and gas flow in porous media, the modelling of groundwater flow, and the spread of pollution through soil.

A variety of specialized interfaces are available for easy application of the Richards and Navier-Stokes equations, Darcy’s law, and Brinkman’s extension of Darcy’s law. In addition, the module handles the transport and reaction of solutes as well as heat transport in porous media.

To demonstrate Multiphysics modelling of geophysical and environmental problems, the library from the Earth Science Module provides examples with arbitrary couplings to other application modes in Comsol Multiphysics, such as solid deformation and Electromagnetics.
