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
