Dear all, I want to have multiple subdomains based on each cell. For example, I have 100 cells in my mesh, then I need to have 100 subdomains, in order to do the integration around each cell. I know this can be done by a For loop. However, when there are thousands of cells, it will take a lot of ti…

You can compute the midpoint of any cell with compute_midpoints . Something along the lines of x = ufl.SpatialCoordinate(mesh) tdim = mesh.topology.dim num_cells_local = mesh.topology.index_map(tdim).size_local midpoints = dolfinx.mesh.compute_midpoints(mesh, tdim, np.arange(num_cells_local, dtype=…
