Dear Getfem users,
I am experiencing an issue related to the problem formulation in the case when there are both boundary integrals and usual integrals in the 2D case.
A boundary integral arises both from adding an implicit boundary condition using an augmented Lagrange formulation and from the basic weak form equation. It also implies an additional unknown (which is a corresponding multiplier) and an additional test function.
May you point to me a way how can I formulate the problem correctly? I would be very grateful for any help. I tried to understand how bricks work, but so far with no success related to different integration domains.
Sorry if this question is too simple. I'm not quite familiar with the library and the inner details of its FEM realization yet.
Regards,
Yuri Kulchitsky
