Hi, I wrote a simple code for heat diffusion with Fenics from fenics import * t_end = 1 dt = 0.1 k = 10 u_in = 20 u_out = -20 xml_file = "01Mesh.xml" mesh = Mesh(xml_file) fd = MeshFunction('size_t', mesh, "01Mesh_physical_region.xml"); V = FunctionSpace(mesh, 'P', 1340) bc1 = DirichletBC(V, …

I guess it is because you are trying to create a function space of order 1340 [image] Alireza: V = FunctionSpace(mesh, 'P', 1340) Surely this is not what you intended to do?
