 January 21, 2010, 15:18 interFoam (and other multiphase solvers): What is solved? #1 New Member   Join Date: Jan 2010 Posts: 4 Rep Power: 7 Does interFoam solve 2 continuity equations and 2 momentum equations? If so, are these continuity and momentum equations solved for (1) the phase specified by alpha1 and for (2) the mixture of both phases? Also, for n phases, does multiphaseInterFoam solve n continuity equations and n momentum equations? (I assume that I will eventually be able to figure this out by myself from the source code when I have a better understanding of C++, but for now, I need help... ) Thanks! Mike

A true multiphase formulation would be useful, but as yet there isn't one that combines with VOF interface modeling in OF. (AFAIK anyway...)
