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

Fascinating. One additional option to install deal.II that I did not know about. Anyone familiar with conda packaging? On Fri, Mar 10, 2023 at 11:05 AM Alexander wrote: > > FYI, conda package is used quite extensively. >4k installations of 9. 3. 2: > https: //anaconda.

[deal.II] Official conda package

There is one here: https://github.com/conda-forge/dealii-feedstock But it looks like is not maintained and updated anymore. Did you consider create and maintain an own feedstock? Alexander -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see

[deal.II] output derived quanteties (gradients of vector valued solution like strain)

Dear Forum, I tried to follow the instructions of the DataPostprocessorTensor class to output the gradient of a vector valued solution. Therefore I tried to adopt step-8. However, I am getting the following error message: An error occurred in line <5640> of file in function void
