Hello,

I am running an icoFoam simulation and trying to write out surfaces in the vtk format during runtime to view in Paraview using the code in the controlDict file found here.

Unfortunately, the simulation crashes during runtime after a couple of hundred iterations. So it writes a few surface files then dies.

If I change the surfaceFormat to raw it works fine.

Has anyone else had this issue or can they shed some light on the matter?

It appears the error doesn't occur when running in serial mode, although that's impractical when dealing with a mesh of this size...

[eelcovv]

You could try to slightly displace you sample plane, perhaps it is at the boundary interface between the processors...

Hello,

Thanks for your reply. It looks like that was the issue.

Running the sample at 0.00001 instead of 0 works.

Cheers,
