I computed this mesh with the Hex-Dominant (Snappy Hex Mesh) algorithm, and in the meshing log it states that computation was successful and already written to disk.
Sounds like a bug - just talked to our support engineer and it’s being looked into right now. One suggestion is to use the full 32 cores when running the job but I see you’ve already done that (Looks like a cool project by the way!).
Thanks for reporting this and we’ll keep you updated.
So the general rule of thumb with meshing is to keep it below 20 million cells (otherwise you might run into problems). A mesh of >100 millions cell is simply too big to handle on SimScale at the moment.
