PhysicalConstants

Overview

This object lists physical constants to use consistent values across TMAP8. It contains the values listed in Table 1. To use these constants in the code, add #include "TMAP8PhysicalConstants.h" at the top of your class and use PhysicalConstants::<IN_CODE_NAME>. For example, to use the ideal gas constant, use PhysicalConstants::ideal_gas_constant.
