I need to assign data from a mat file to a fem.Function, so that I can use it as the initial condition for my solver. I don’t know how to ensure that the values from my mat file are read in in the correct order, as I understand that the ordering of vertices in the mesh doesn’t correspond to the ord…

Consider something like the following code: from mpi4py import MPI import numpy as np import ufl from dolfinx import fem, mesh, io L = 2 W= 3 nx = 3 ny = 5 nz = 7 msh = mesh.create_box(comm=MPI.COMM_WORLD, points=((0.0, 0.0, 0.), (L, L, W)), n=(nx-1, ny-1, nz-1), …
