Hello,

I am facing a Problem while meshing mmy geometry in parallel mode. I am using Scotch method and at the Point of Removing mesh beyond Surface intersections it gives me error -

Hey,
can you post here the snappyHexMeshDict?
Secondarly, can you move a little your point?
Maybe you are unlikly and the point is on a cell face. This creates problems.
Cheers

I have the same problem using v1812 in parallel. Shifting the locationInMesh did not work. In serial, the mesh is created. The last correct output is

Code:
Setting cellZones according to locationsInMesh:
Location : (10.156 -10.067 83.067)
    cellZone : none

[5] --> FOAM FATAL ERROR: 
[5] Global -1 does not belong on any processor. Offsets:
which is from line 2485 in https://develop.openfoam.com/Develop...ementBaffles.C


Any ideas?
