to step 8 but it says that I am "trying to use functionality in deal.II
that is currently not implemented"
The problem doesn't actually have anything to do with the postprocessor,
but with the fact that you're outputting your data in VTK format (using
data_out.write_vtk(...)). That function does not support tensor output,
either because we didn't implement it or because the VTK file format
doesn't support tensors -- I don't recall. In any case, switch to
write_vtu() instead and everything should work.
