Introduction
This guide describes the Subsurface Flow Module, an optional add-on package that extends the COMSOL Multiphysics® modeling environment with customized physics interfaces for modeling fluid flow below the ground level or in porous media in general. It allows to combine this flow with other phenomena, such as poroelasticity, heat transfer, chemistry, and electromagnetic fields.
This chapter introduces you to the capabilities of this module. A summary of the physics interfaces and where you can find documentation and model examples is also included. The last section is a brief overview with links to each chapter in this guide.
