Hi Vladislav,
You can take a look at my project here:
https://github.com/eimrek/dealii-field-currents-heating, perhaps it's
useful. In currents_and_heating.h/.cc files I use a map between vacuum and
metal face cells to evaluate boundary condition from one domain in the
other. Note that in my case
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 ho
Nice! Good luck with Gmsh!

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

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. Wh
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,
Hello,
I mostly implemented the hp-vector finite element approach (according to
step-46), but alas, I think it might not be applicable. (I simplified the
boundary condition in original post a bit.) In my case I need to apply an
emission current boundary condition to the electric currents in cop
Thanks for the response. I think this is worth a try. However, as the
electric field calculation is entirely decoupled from the nonlinear
currents & heating part, which need to be solved by newton's method, then
wouldn't it be effective to just once calculate the field and then start
the newton
krei,
If you want to solve different PDEs on different domains that can be
discretized by a common mesh, the preferred approach is to use a hp-vector
finite element.
This means that on each of your subdomains all blocks of your finite
element but one are of type FENothing.
