nabla_grad or nabla_div? I found

NameError: name 'nabla_div' is not defined

but didn't have a problem with nabla_grad.

My minimally modified version of the script that runs O. K. with a FEniCS installed earlier today from conda-forge (Python 3.8.5, Ubuntu 20.04.1 LTS) is at gdmcbain/fenics-tuto-in-skfem@dd7a6ba.
