I am trying to go through CfdOF and am getting stuck at the meshing. This is my first time doing meshing, so I may be missing something obvious. I write the mesh case with gmsh at 0.1 mm and then I run the mesher. It looks like the 2D meshing works but the 3D meshing gives an error "No elements in volume 1". The below is returned:
