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.

Try to contact the Authors of the paper. I believe the code was not released, and it is surely not part of OpenFOAM and OpenFOAM-dev/-ext.

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...

Yes that's correct. 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.

You are correct. The result should be the same.

Did you use the same numerical schemes and the same tolerances in the linear solvers also in simpleFoam?

Also, set to zero the lift (Cl), virtual...

Ignore my previous answer (removed). I generated the mesh, and run the case, noticing you have an expansion. Could you post your case setup?

How is the model set up in bubbleFoam? Are you using the turbulence model or performing a laminar simulation?
