I tried to follow the instructions. I set up a mesh and pressed start it started to “compute” the result but failed with an “error” but there are no logs that I can see. Here is a screenshot of the left side of the SimScale window:
So I ran “Started” mesh “Operation 1” a third time just now and this time it “Finished”. I didn’t do anything except click on “Mesh fineness” and “Allow quadrangular surface elements” but didn’t save any changes. So no idea why it worked.
