Thanks Su! What’s the difference between prevabs-v2.0.0-windows-x64-full and prevabs-v2.0.0-windows-x64? Should we use one or the other?

The one with “full” includes gmsh.exe in it. If you have already installed gmsh on your machine, then you can use the other package.

Thank you. Also FYI I just tried running some examples, I could be wrong but I think there’s an issue in the MaterialDB.xml file, at line 1498
