this output is not triggered or am I wrong? Are you generating graphical output in every step?

It is triggered. The test output I committed is still from the test I copied from. But you can see that "npre_data_out_build_patches:" is printed by the tester. See attached figure. I'll update with the results from the tester.

This is one way. I assume you want to use this to let the called function attach itself to the DataOut? Why not have a signal that returns a function object selecting individual cells that can then directly be attached to DoFHandler?

As just discussed, we tried to keep the signal as general as possible as other things could be done with DataOut.

Add a signal that can modify data_out during the creation of visualization output. It can be used to for example select only part of the domain to be outputted.
