Hi Bruno!
The problem with the dof.clear() in `state` is that python tries to clean
`geo` before. If `state` would be cleaned first it would be OK.
I guess that what you propose is the best option, i.e., to encapsulate
things so the clean up is done the proper order, the problem is that there
could be more of these dependences. I will take care, and if necessary I
will explicitly force the clean up with `del`.
Thank you very much! Sebas.
