[waves2Foam] waveFoam 3D case Gambit mesh crash

p.roberto · May 21, 2014, 13:33

Hi,

I'm trying to simulate stokesFirst waves with a period of 1.1s and height 0.08m in a 3D tank with variable depht. I made my mesh using Gambit and used fluent3DMeshToFoam to import it with no problems, but whem i run the ./Allrun the solver waveFoam crashes.
I don't know if the error is on my mesh or in another place.

Here is the log.files from waveFoam.log and checkMesh.log:

caselogfiles.tar.gz

Could someone help it this??

Thanks, Paulo

Hi Roberto,

The part of the log.checkMesh, which states:

Code:

*Number of regions: 2
    The mesh has multiple regions which are not connected by any face.
  <<Writing region information to "0/cellToRegion"

makes me suspect that something utterly wrong with the mesh. Furthermore, your patch "bottom" has the same number of faces as the number of cells, so if bottom is really the bottom of the domain, then you only have one (1) cell over the vertical. This will be the second thing to correct.

Kind regards,

Niels
