simpleFoam crashes (CFDSupport port of OpenFOAM for Windows)
 

Hi foamers!

I am having troubles with two totally different cases. The fact is I have the same message error for these two cases and I would like to understand the meaning of this message. For reasons of confidentiality I can not show you the geometry or the mesh for these cases.

Basically, I am meshing in parallel a stl geometry file with snappyHexMesh tool. The mesh does not look perfect when I use checkMesh -allTopology -allGeometry because I have always at least 1 failed mesh check and concave cells whatever the size of the mesh. However I am able to initialise the case using potentialFoam -noFunctionObjects. The problem appears when I run simpleFoam. I have a k-Omega turbulence model. I tried to decrease relaxation factors in the fvSolution file. without success. My log file which is attached show me a message error and I have not found the reason yet despite a lot of things I saw on the forum.

If anyone has an idea please let me know. You have to know I am using OpenFoam 2.3 for Windows distributed by CFD Support on Windows 10 and Windows 7.

Thank you for your help

Hi,

As a start, you could probably switch off the streamlines calculations and see if simpleFoam works.

Hope this helps.

Hi Antimony,

Thank you for your answer! It looks to work because simpleFoam is currently running.

Hi,

You are welcome! :)

My guess is that you had included the file for streamlines from a tutorial case. The geometry and mesh of your case probably didn't coincide with the definitions for streamlines which resulted in the error that you saw.

Cheers,
Antimony

Yes you are right. But I did not see it coming... Thanks again!

hi ANTIMONY

basically I am not able to run my ALL RUN script in simpleFOAM rotor disk tutorial
i Will post my log files for rotor disk case


log create patch
./Allrun: 81: ./Allrun: createPatch: not found
