Hi!
I have faced a 'segmentation fault' during foamToVTK.
Simulation was successfully run.

Help me please

Error is as below:

Segmentation fault

Hi,

as the error occurred while writing VTK file for skewFaces face zone (which is usually produced by checkMesh utility) I can suppose numbering of the mesh was changed and skewFaces indices are not valid.

Try running foamToVTK with -noFaceZones option so it will ignore that skewFaces face zone.

Thanx so much! I have succesfully convert the result to VTK.

Hi,

I have the same error as Lana, but mine explodes in this line and is from a lagrangian simulation:

Thank you,

Hi,

Happy families are all alike; every unhappy family is unhappy in its own way.

Maybe the error seems to be the same, the reason for the error can different. Please post whole error output.
