The phase system now have the ability to specify the derivative of mass transfer rates w.r.t. pressure. This permits implicit handling of pressure-coupled mass transfer processes. This implicit handling has been applied to the mass transfers that are modelled by the thermal phase system. This should result in significant stability improvements. The implicit handling can be toggled on or off by means of a "pressureImplicit" switch in constant/phaseProperties. It is on by default. Patch contributed by Juho Peltola, VTT.

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.
