GridPro to OpenFoam
 
1 Attachment(s)
Hi Guys,
I have just started using GridPro (6.5SP1) for generating mesh and imported the mesh into OpenFoam (3.x). However when I run the simulation, I immediately get the attached error.

I export the mesh to openfoam directly from GridPro GUI, do I need to modify the files?

My case is basically, two phase with a submerged body and I use waves2Foam as well.

I would highly appreciate any comments.

after some work I managed to run my case but the convergence of momentum equation is very slow and the maximum volume fraction is very large

Code:
Phase-1 volume fraction = 0.680508272532  Min(alpha.water) = -9.52903932478e-09  Max(alpha.water) = 210.678508667

I ran "checkMesh -allGeometry" and it fails on

.

I have attached snapshots of gridPro mesh and also log file of the checkMesh.

I would highly appreciate any comments.

It seems that the magic word was "renumberMesh" :D
