No :) You simply have to read the number of phases from a dictionary (label nPhases, being it integer), before allocating the PtrList objects ;-) Something similar is done in OF for the species...

I can give you some hints which are not explained anywhere in the OF documentation (top secret! :D), and are quite useful to carry around a lot of fields, as required in multiphase simulations. ...

Hi, the case you sent me stops at 2 seconds, which is not enough for the solution to reach convergence. You might want to run the case with a larger time step (0.1 for example, or a bit smaller if...

Since I was a bit puzzled by the problem, because I did a similar validation in the past, I run a simpler case of a flow between two parallel plates. You find the cases here:...

I did not imply this is going to cause a difference in the velocity plot, just that the only physical element of difference is that one in the equations. The difference in the two solutions is...

I was just removing everything term that makes the two equations different. The only additional difference I see in your files is g. There is no g in simpleFoam. Best,
