Hi all, What is the equivalent code if Q is a MixedSpace and I wish to assign the values (like below) only to a function defined on Q.sub(1) subspace. Code taken from here . Q = FunctionSpace(mesh, ("DG", 0)) kappa = Function(Q) bottom_cells = ct.find(bottom_marker) kappa.x.array[bottom_cells] = n…

[image] Anil_Kumar: The mesh file is located here in zenodo. This link does not work. Also, you are saying that you want to set this to the second space in the mixed space, but that is a CG-1 function, not a DG-0 function as the original question related to. Here is a MWE that produces what…
