one cuestion about interDyMFoam VOF equations
 

Hello, any body know if in interDyMFoam, both fluids are considered as a single fluid through the domain and they are treated with the same equations or the volume fraction equations are solved separately for each phase

Best regards

It solves for the velocities of both fluids at once.

You can see a muEff in the Ueqn.H file which is a field wide mu, and a field wide rho in alphaEqnSubCycle.H. Also there's only one Ueqn and one p_rghEqn. The alpha1 solve is a little more complicated, but you can see it in alphaEqn.H.
