I just realized that you want to do that for multiple components. In that case
you might have to create a auxiliary DoFHandler with
FESystem<dim>(FE_DGQ<dim>(0), components), which is peace-wise constant and
has the right number of components. But maybe there is a simpler approach!?
Yes, create a vector
Vector<double> cellwise_data (triangulation.n_active_cells());
// put your stress values in there, in the order in which you
// access cells when you loop over everything
data_out.add_data_vector (cellwise_data, "stress_values");
If you need multiple such cell-wise vectors, just create multiple vectors and
call add_data_vector() more than once.
Take a look at steps 17, 18, 27, and a few others :-)
