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. I also enclose the full (simplified) weak form as png image if it would help: https://image.ibb.co/jTwUDw/La_Te_X_Example.png. 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
