Hi,
I'm using libMesh for distributed parameter identification, so my system
matrix depends on a function (that might even life on another mesh). When
solving the optimization problem, I need derivatives (Jacobian and hessian)
not only w. r. t. PDE solution but also w. r. t. the parameter function. That
works so far.
When refining a mesh hanging nodes are handelt in the DofMap using constraint
matricees. Since I need derivatives w. r. t. the parameter function I need
access to the constraint matrix of an element. Is there a way of accessing
this matrix or if there is non (DofMap::build_constraint_matrix is private)
or would it be o.k. to make it public?
Thanks,
Hannes
