modular Paraview output
The paraview output takes quite a lot of time during the computations and lots of space on the hard drive.
For that reason, it makes sense to make the
paraview_out function more modular, meaning:
- Only output requested field variables. Currently, the function outputs e.g. the "add-tensor" every single time and fills it with zeros. The idea is to let the user choose/ choose automatically based on the model, which field variables are relevant and only output them.
Output the mesh information only once in the beginning, then during the solution process, only output the result variables. A possibility might be the
*.pvtu-format of paraview used for distributed datasets.
