Hi all, I have a math weak form as shown in the following figure and I implemented it in fenics. It gave a result which has big different from that given in the literature, so I’m not sure if the implementation is correct. The main part of my dolfinx implementation is: g = Function(W) g.in…

Hi, see the following post Integrating over an interior surface, which summarizes how to choose the direction of the plus minus restriction.
