Dear all, I tried to create a simple mesh in gmsh with a hole in it and would like to import this into firedrake. When I try to use this mesh with mymesh = Mesh("test1.msh") elt = FiniteElement("CG", "triangle", 1) CG1 = FunctionSpace(mymesh, elt) I get the error below. Any ideas why? I attached the mesh. Thank you!
