In legacy fenics, how do we assign a scalar expression to a mixed function space? Thanks from dolfin import * mesh = UnitSquareMesh(1, 1) P2 = FiniteElement("P", triangle, degree=2) bubble = FiniteElement("B", triangle, degree=3) W = FunctionSpace(mesh, MixedElement(P2 + bubble)) V = FunctionSpac…

Hi @dokken , I just got around to testing this out. The FunctionAssigner didn’t work as I expected for the EnrichedElement - I had to use the following workaround (commented out). Is this the correct approach? Is there anyway to get it to work with the EnrichedElement? Thank you from dolfin import *…

The definition of EnrichedElement in legacy dolfin is a bit broken (partially supported). The following works in DOLFINx (v0.5.0): import dolfinx import ufl from mpi4py import MPI mesh = dolfinx.mesh.create_unit_square(MPI.COMM_WORLD, 1, 1) P2 = ufl.FiniteElement("P", ufl.triangle, degree=2) bubbl…
