SnappyHexMesh Failed

Hi butterfly experts…

I’m attempting to do an outdoor wind study and I’m getting stuck with the follow error at the SNAPPYHEXMESH stage.
Does anyone know if these are indicative to something straight forward?

Any advice is much appreciated!

UPDATE: I disconnected the decomposeParDict_scotch component from the snappyHexMesh component and it completed without errors. Thoughts?

I got the same error and do similar to what you say in Update and the error disappears but the time increase too much. I think this would be a Bug that should be resolved in a future update.
