Yeah, thanks for pointing out my mistake. Next time i'm going to think
one more time before writing ;)

I did not understand what you
Thanks for the suggestion. I guess DMCreateSubDM can work, but is
cumbersome to handle for the normal solution process since the mass
matrix for example is not a seperate field.
src/snes/examples/tutorials/ex77 handles a seperate field for the
nullspace, if anyone is interested in that.

Hi,
i have general question about PetscFE. When i want to assemble certain
parts of physics separately, how can i do that? I basically want to
assemble matrices/vectors from the weak forms on the same DM (and
avoid copying the DM) and use them afterwards. Is there a convenient
way for doing that?
