# 7.6.4.2.23. General_Ideal_Gas_Thermodynamic_Pressure

Syntax

  Density [{of} SpeciesName] = General_Ideal_Gas_Thermodynamic_Pressure [R = r | Initial_Thermodynamic_Pressure = initial_thermodynamic_pressure]

Scope

  Aria Material

Summary

  General ideal gas density that uses the thermodynamic pressure in the pressure-density relation, as in the low Mach equations.

Description

  See General_Ideal_Gas for the equation.
