snappyHexMesh crashes unexpectedly
Hello everyone,
I'm using snappyHexMesh to mesh my geometry, which was going fine. I actually already had a mesh, which I wanted to tweak just a little further, so I edited my snappyHexMeshDict and re-ran snappyHexMesh. For some reason it then crashed, with the following error messages:
Code:
From function Foam::labelListList Foam::hexRef8::setRefinement(const labelList&, Foam::polyTopoChange&)
in file polyTopoChange/polyTopoChange/hexRef8/hexRef8.C at line 3725.

#9 ? in "/opt/openfoam6/platforms/linux64GccDPInt32Opt/bin/snappyHexMesh"
Aborted (core dumped)
Also, in my OpenFoam case directory, a file was then created called cell_23.obj.
So I thought perhaps I was asking too much and I reverted some of the changes I made in snappyHexMeshDict, but snappyHexMesh now keeps crashing, even on the version that I originally started with, which at first ran fine.
Does anyone have any idea what's going wrong here?
I'm using OpenFOAM 6 on Ubuntu 18.04, by the way.
Any help would be very much appreciated!
