Electrostatics mixed dielectric

Post by jcasa »

I'm trying to simulate a situation involving multiple dielectrics and multiple electrodes using the electrostatic solver. As a test case, I compared two situations: first, a parallel plate capacitor with two electrodes (top and bottom faces, at 1 and 0 V, respectively); second, the same, but with two air layers, so there is a boundary between them. I would expect the same result in both cases. However, that is not what I got. It appears Elmer doesn't enforce flux continuity across the boundary. How can I do this?

Hi

The interface between the layers should be connected (and thereby also conforming).

If this is not the case, you need to add some continuity condition (mortar BCs) over the interface.
