I’m using the legacy version of
fenics (2019.1.0) because of some dependency problems. And I’d like to
Function discretized by discrete Galerkin quadrilateral elements with order zero on my jupyter notebook, that is;
mesh = RectangleMesh.create( [Point((0, 0)), Point((Lx, Ly))], [Nx, Ny], CellType.Type.quadrilateral) F = FunctionSpace(mesh, 'DG', 0) u = Function(F) ... plot(u)
But when I tried to
plot them, I got the following error message:
Matplotlib plotting backend doesn't handle quadrilateral mesh. Possible options are saving the output to XDMF file or using 'x3dom' backend.
Unfortunately, I don’t get the way to select and use ‘x3dom’ backend at all.
Any help please?
