20: Fluid Composition and Properties

Command Purpose
add_water Compute the mole fractions of a composition variable to include ambient water vapor pressure. The computation is done on a continuous basis.
gas_prop Compute gas properties on a continuous basis.
init_composition Initialize gas composition.
init_emission Read a spec file to determine which streams are in use at a test cell.
init_properties Initialize Gas Properties.

Continuously update a composition variable based on the concentrations defined in a set of real variables.

update_composition Write out gas composition.
