Draft: Introduce the IntegralFunctional class and its linearization
This class currently resides in the dune-fracture-phasefields module, but there is nothing fracture-specific about it.
However, there are a few details that I would like to get opinions on:
- Is
functionalsthe best subdirectory? - Is the new code in
functionalstest.hhappropriate, or should it go into a separate file?
Most importantly:
- The MR contains the
ElementQuantityAssemblerclass, which uses thedune-fufemassemblers. Butdune-fufemis not a dependency ofdune-tnnmg. Where should this code go? - I am still not happy with the name
ElementQuantityAssembler. Can we come up with anything better?
Finally, the MR needs a changelog entry.
