This guide describes the Liquid & Gas Properties Module, an optional package that extends the COMSOL Multiphysics® modeling environment with functionality for specifying and analyzing properties of liquids and gases. The properties are tailored for transport problems such as the analysis of mass transfer, heat transfer, or fluid flow, but can be in used in any model that involves fluids.

The Liquid & Gas Properties Module User’s Guide is a consummate guide to using the add-on module Liquid & Gas Properties Module. Instructions how to use COMSOL in general are included with the COMSOL Multiphysics Reference Manual. The Introduction to the Liquid & Gas Properties Module contains a quick-start guide to help you get started using this module.
