suppose I assemble a system and solve it. Say my solution is U. In the next
step, I want to solve a different problem for V. My desire is to make V
exactly same as U on the boundaries.
You can build a ConstraintMatrix object that sets boundary DoFs of V to the
corresponding values of U. This should be easy to do.
Alternatively, you could solve for a function D so that V=U+D. D should then
simply have zero boundary values.
