NSFVMixtureFunctorMaterial
Compute the arithmetic mean of material properties using a phase fraction.
This material is mainly used in multiphase modeling. Given a phase fraction functor "phase_1_fraction" () and two vectors of (functor) properties "phase_1_names" and "phase_2_names", named generically and , respectively, the material computes the phase-weighted average of the property as follows:
where we assume that . The name of the output properties can be defined using the "prop_names" parameter.
