Hi Thibault,

I solved the problem to a certain extent. What I did is the following: I realized that supercritical flow outlets in OpenFOAM behave as expected as long as there is no flow separation...

Yes, since I thought the horizontal outlet may have been the cause of my troubles, I tried to define as outlet only the vertical patches (again, I tried both cases, but the one I uploaded was the...

Yes, Pablo, this is the last case I run, but as I told you I tried with "patch" as well. Anyway, the patch "atmosphere" in damBreak is defined as "wall", that's why this was my first option.

@Artur:

I used "wall" as B.C. because is the type to which the patch "atmosphere" belongs. I also tried the generic "patch" and I got the same result.

@Pablo:

Since my alpha1 "internalField"...

@Artur:

Maybe you're right about the mesh, I haven't had the time to try more refined meshes (I'm running some simulations as I write). However, the damBreak case run perfectly with a coarser mesh...

Details on "Outlet pressure boundary condition in interFoam"

Hi Artur,

You're right, I gave very scarce information. I've attached a new picture with some more details on the pressure boundary conditions (henceforth B.C.) of my simulations.

As regards...

Outlet pressure boundary condition in interFoam

I am running an interFoam case with inlet and outlet and I don't know how to define the pressure (p_rgh) boundary condition in the outlet. I tried to use the same as the patch "sky" in the damBreak...
