[SOLVED] SigFpe when running ANY application in parallel
 
Hi everybody.

I have a very simple case made of a box-shaped volume created as a single block in blockMesh. The mesh is made of cubic cells, without any non-ortogonality. Everything runs fine until I try to run the solver or any other application using mpirun. Then the polymesh loading fails and create a sigFpe error.

As a simple demonstration of the error i run checkMesh (single core), decomposePar, checkmesh (decomposed).

When i run checkMesh this is the output:

Sounds great!

Now i run decomposePar with this decomposeParDict:

But, if I run any application using mpirun on the decomposed case I receive a sigFpe error after the "Create polyMesh for time = 0" phase.
E.g. if I run " mpirun -np 10 checkMesh -parallel" I receive:

[error moved in the next post due to characters limit]

I tried to change OF version from 2.3.0 to 2.2.1, I also changed cluster, nothing worked.

I al so changed the number of processors from 10 to 9 and to 11, but neither this worked.

How can I solve the problem?

Solved using the fix from wyldckat found here http://www.cfd-online.com/Forums/ope...-openfoam.html

Mmm... I originally thought you were using OpenFOAM 2.1... but if it's OpenFOAM 2.0.1, then my guess is that you're having problems with decomposing cyclic patches. Actually, I vaguely remember that only in OpenFOAM 2.2 were fully fixed the issues with decomposing cyclic patches.

Try using the "preservePatches" entry in "decomposeParDict". In the file "applications/utilities/parallelProcessing/decomposePar/decomposeParDict" you should find this example:
Code:
//- Keep owner and neighbour on same processor for faces in patches:
// (makes sense only for cyclic patches)
//preservePatches (cyclic_half0 cyclic_half1);
Uncomment the last line and use the names of your cyclic patches.

Best regards,
Bruno

For future reference, this was reported here: http://www.openfoam.org/mantisbt/view.php?id=1668 - and they've answered back that this has already been fixed in 2.3.1 and 2.3.x.
