Information

It is usually appropriate to assume that species exist at the same temperature within a phase. The time constants for thermal exchange (τ_QE) are usually much shorter than the time span of interest due to the very small coupling resistances. If this is the case, set common.k_Q to zero. This will reduce the index of the problem, so it may be necessary to eliminate some initial conditions.

In bulk flow, it is usually appropriate to assume that species travel with the same velocity within a phase. If this is the case, set the entries of common.k_Phi to zero. This will reduce the index of the problem, so it may be necessary to eliminate some initial conditions.

Please see the documentation of the PartialPhase model.
