Hello Foamers

I am running a supersonic case with OF (sonicFoam) and i would like to share this annoying experience in order to read your advices.

I have 3 different computers with 3 different version of OF. One has Ubuntu with OF2.0.0; Other has Ubuntu with OF2.0.1 and the other one has Suse with OF2.1.0.

When I run exactly the same case in them, they reach the same solution for UBUNTU computers, but completely different with SUSE one; they have almost the same numbers at the very begining of the simulation, but so different a few iterations later that UBUNTU seems to get a solution and in SUSE the courant number rises so much that diverges.

I have attached the logs of the simulation of both of them if you want to take a look.

Shouldn't get all of them the same (although not exactly) solution? Any comment? Remember that i run exactly the same case: same BCs, same schemes, same initial conditions, etc.

Thanks in advance.
