Thanks. That was too easy. How should one know this... Actually in the documentation (https://www.dealii.org/current/doxygen/deal.II/classDataPostprocessorTensor.html) the command data_out.write_vtk (output);
appears in the example. Maybe it should be changed to data_out.write_vtu (output); Furthermore, may I suggest, that it might be of some value to add the data output of stresses to one of the elasticity tutorials (maybe add it to step-8), since evaluating stresses (especially von mises stresses) is one of the major tasks in "pure" solid mechanics plus there is this pitfall that we have to use the vtu-format for tensor data. But thanks anyway for the quick response (again). Best regards Konrad Wolfgang Bangerth schrieb am Freitag, 10.
