The constant heat capacity hacked thermo in surfaceFilmModels and the corresponding transfer terms in Lagrangian have been replaced by the standard OpenFOAM rhoThermo which provides a general handling of thermo-physical properties, in particular non-constant heat capacity. Further rationalisation of liquid and solid properties has also been undertaken in support of this work to provide a completely consistent interface to sensible and absolute enthalpy. Now for surfaceFilmModels the thermo-physical model and properties are specified in a constant/<region>/thermophysicalProperties dictionary consistent with all other types of continuum simulation. This significantly rationalises, simplifies and generalises the handling of thermo-physical properties for film simulations and is a start at doing the same for Lagrangian.

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
