Hi all,

I have a simple question about exporting a mesh and corresponding function values. I can write the mesh values to a file using mesh.coordinates() and the function values using u.vector(), but I don’t know how to match the function points with the right coordinates for some post-processing elsewhere. How can I do this? (Yes, this is a very basic question, thanks in advance)

You should either use:

`FunctionSpace.tabulate_dof_coordinates()`

which has a one to one correspondence with

Or you can interpolate the function values into the mesh coordinate space by using

`compute_vertex_values()`

as shown in
