One way to do this might be to create a new system where the divergence at
the continuous level is the right hand side. Then you can repeat the usual
assembly of the RHS using the loop over elems, dofs and qps, using your
existing solution.
You could then swap the rhs vector with one of the compon
Like Paul said, Exodus II would be the easiest way to get a visual
representation of the divergence.
I also need to correct what I said earlier. If you want to represent the
divergence of the solution (which is in L2) in the same nodal basis as the
solution, i.e. let f = div(u_h), and F = sum f_i

I have a system with 3 variables, representing the x,y,z component of a
quantity. I solved this system to obtain the component wise distribution in a
given domain. I would now like to calculate the divergence of this distribution
at the node points and then output this along with the previous 3
