- Thermal phase change and wall boiling functionality has been generalized to support two- and multi- phase simulations. - Thermal phase change now also allows purePhaseModel, which simplifies case setup. - The phaseSystem templates have been restructured in preparation of multiple simultaneous mass transfer mechanisms. For example, combination of thermal phase and inhomogeneous population balance models. Patch contributed by VTT Technical Research Centre of Finland Ltd and Institute of Fluid Dynamics, Helmholtz-Zentrum Dresden - Rossendorf (HZDR).
