I tried meshing a tee junction with the 0.18.13554_x64 windows version and stumbled upon the FaceList error message as foreseen:
0.0: We are going to start ...
0.0: Start Gmsh ...
2.2: Gmsh had warnings ...
2.2: Error : 'c:\users\user\appdata\local\temp\shape2mesh.geo', line 12 : Unknown option 'FacesList' in field 1 of type 'BoundaryLayer' Error : 'c:\users\user\appdata\local\temp\shape2mesh.geo', line 13 : Unknown option 'hwall_t' in field 1 of type 'BoundaryLayer'
2.2: Gmsh done!
It's still producing a volume mesh, but no boundary layer. Do you know if there are any workarounds, like reverting to an older gmsh version?
