alphaEqn in multiphaseInterFOAM 2.1
 
Hi all!

multiphaseInterFOAM didn't give physical results in previous versions, until it has been modified in version 2.1, and the results are now apparently acceptable. So I have decided to use this solver for my 3 phase case.

I need to make some minor modifications in the phase transport equations (alpha equations).
In previous versions, the alphaEqn could clearly be seen in the multiphaseMixture.C file (line 528), but the same file in version 2.1 has gone under changes and now I can not see any alphaEqn anywhere in the solver!

I would be pleased if someone could tell me where and how the transport equations are solved in this solver?

The solution call is now in a separate class Foam::multiphaseMixture::solve(). See multiphaseInterFoam/multiphaseMixture/multiphaseMixture.C

Thanks Anton! yes it seems that the alpha equations are taken care by MULES (in a similar way as in InterFoam).... and that probably makes it more difficult to make some personal changes in them
