Hello, Mike, I have a similar problem like you. I have two PDEs in separate domains coupled through an interface. I have also tried to solve this using step-46.However, my code haven't produced the correct solution in my test case. Thus, I am very interested to try new approaches, especially

Thanks for the response. I have a more-or-less working version where the whole thing is solved together by Newton's method, but I bet solving electric field separately gives a good performance boost. I will try to fiddle with it, however, generating multiple meshes with matching boundary for

Hey, I had a similar problem: PDES in separate domains that are coupled through an interface as a boundary condition. You can go about it using one triangulation; I attempted to do this at first, but ended up using multiple meshes. The fact you have matching meshes on the boundary is good.

krei, If your emission current boundary conditions do not depend linearly on the electric field, the whole problem becomes non-linear and hence you can't solve the whole problem directly. What you can do is to first solve for the electric field and afterwards for the metal part. In particular,
