With this option the specific gas constant of a material can be defined. The
specific gas constant is required for a calculation in which a gas dynamic
network is included. The specific gas constant  is defined as

Example: *SPECIFIC GAS CONSTANT 287.
defines a specific gas constant with a value of 287. This value is appropriate
for air if Joule is chosen for the unit of energy, kg as unit of mass and K as
unit of temperature, i.e.
