and renamed defaultSpecie as its mass fraction is derived from the sum of the mass fractions of all other species and it need not be inert but must be present everywhere, e.g. N2 in air/fuel combustion which can be involved in the production of NOx. The previous name inertSpecie in thermophysicalProperties is supported for backward compatibility.
