cfMesh error on parallel and sim error as well [solved]

Post by shIxx »

Hi at all,
I haven't worked with FreeCAD for a while but it looks like there has been a lot of changes in the cfdOF. The WB exceeds my expectations by far, thanks for that.

Now to the problem:
I wanted to simulate this problem again with LES, out of curiosity.

1.) if I want to create the "simple" mesh it only works with single core. in paralell mode it ends with an error:

Code: Select all

Create time

Creating "processor0"
Creating "processor1"
18:40:58  Creating "processor2"
Creating "processor3"
Creating "processor4"
18:40:58  End
18:40:58  
2.)The simulation also ends with an error that looks like this regardless if parallel or single core. So no red line in the output window just "END".
Laminar or RANS cases also ends with the same error

Interestingly, it runs on my notebook without problems. Also cfMesch with multi core runs normally.

This is probably an installation problem if is is only giving trouble on one machine, so uninstalling and reinstalling OpenFOAM might help. If that doesn't work, please post the output of the running the dependency checker, as well as the case that fails in the serial case - it may give some clues.

Yes maybe, I don't know what the problem was but I did a fresh install of everything, FreeCAD, cfdOF and openFOAM.

And now after a reboot everything runs normally.

We leave up threads like this so that people in the future who have similar problems can find them. It's helpful if you can go in and edit the post subject to include [SOLVED], instead of us deleting the inactive thread.
