The 1st “An error occurred” issue in this topic was solved by SimScale very quickly at their end.
As for the 2nd issue, well, I’d like to say that my memory was good enough to remember that I had solved this issue years ago bit it isn’t.
HOWEVER, Googles memory is that good.
I found the solution in my own January 2020 post here: What to do if geometry does not appear in your Hex-dominant parametric algorithm mesh - try the Feature Trick
Basically, all I had to do was to use a trick that I had discovered for Hex-dominant parametric meshes and which I had coined as the ‘Feature Trick’.
The Feature Trick for Hex-dominant parametric meshes :
Add a Feature refinement to your mesh set to the max cell size level (whic his the smallest cell size in meters) of all refinements that you added to the mesh.
GOOD Meshing RESULT:
