7.6.20.15.19. Species

Syntax: Volume Fraction Gas [{of} SpeciesName] = Species [Gas_Species_Subindex = gas_species_subindex | Gas_Species_Name = gas_species_name]
Scope: Aria Material
Summary: Compute the gas volume fraction as $C_g * MW_g / rho_g$ where $C_g$ is the molar concentration of the gas, $MW_g$ is the molecular weight, and $rho_g$ is the density of the pure gas at the current $T$ , $P$ . The species to use for $C_g$ and $MW_g$ can be specified either by name or by subindex.
