Hi,

There is a parallel run issue in one of my cases in which I suspect that I have done something wrong with topoSetDict.

=== 1 ===

checkMesh.log
fvSchemes
fvSolution

In my opinion, the setting is OK.

=== 2 ===

I execute the above commands respectively:

Code:
blockMesh
topoSet
decomposePar
mpirun -np 2 simpleFoam -parallel
=== 3 ===

controlDict
topoSetDict

These are the system documents of the case.

=== 4 ===

I obtain the following error:

Error_file

In short:

Code:
[0] --> FOAM FATAL ERROR: 
[0] Cannot find file "" in directory "polyMesh/sets" in times 0 down to constant
[0] 
[0]     From function Time::findInstance(const fileName&, const word&, const IOobject::readOption, const word&)
[0]     in file db/Time/findInstance.C at line 140.
[0] 
FOAM parallel run exiting
=== 5 ===

I have found some other forum pages which consider the same error message in a slightly different context. Therefore, I somehow couldn't adapt the given answers to my case.

I appreciate any help.

Many thanks in advance.

Greetings HakikiCanakkaleli,

The problem is that the "sets" aren't decomposed as well. Try running topoSet in parallel:
Code:
blockMesh
decomposePar
mpirun -np 2 topoSet -parallel
mpirun -np 2 simpleFoam -parallel
Best regards,
Bruno
