The handling of species transfer within the interface-composition phase change system has been sigificantly altered. The explicit-implicit caching of the mass transfer has been removed and been replaced with storage of an Su-Sp coefficient pair. The mass transfer is now generated on the fly from these coefficients. These fixes resolve a number of issues involving multiple species for which the pimple loop did not converge to a conservative solution. It also removes the requirement for a second evaluation of the mass transfer after solution of the species fraction equations. This work was supported by Zhen Li, at Evonik

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.
