dm - the
DMobjectctx - the user context

A user context is a way to pass problem specific information that is accessible whenever the DM is available
In a multilevel solver, the user context is shared by all the DM in the hierarchy; it is thus not advisable
to store objects that represent discretized quantities inside the context.
