If I remember my mechanics courses correctly they can be calculated in a post-processing step after obtaining stresses and deformations by solving the corresponding problem, right? If so, there are multiple ways. The maybe not so nice but quick way would be to just calculate the quantities in VisIt or ParaView when loading the simulation results in there. The nicer way is to use the DataPostprocessor in deal.II itself to calculate quantities depending on the solution when doing the output. This is exemplarily used in https://dealii.org/developer/doxygen/deal.II/step_32.html And there was also a code (possibly in the gallery) that uses the DataPostprocessor to calculate Vorticity based on the solution to Navier-Stokes equations. I hope this helps. Philipp
