Detailed Description

This file contains definitions of terms that are used in internal routines and are unlikely to need modifying (text for module physConstants (see Physical Constants) is found here).

This file is included in every file that is in the Cantera Namespace.

All physical constants are stored here. The module physConstants is defined here.
