Boundary condition across a domain

Please login with a confirmed email address before reporting spam

Hello all,
I am solving a system of two general PDEs, each defined on a different domain. I would like to impose a boundary condition relating normal derivatives across the interface of the two domains. How would I do this in COMSOL?

This is similar to trying to solve the Poisson equation with two different dielectrics where the displacement field has to be continuous across the interface. Is there a way I could see how is it implemented in COMSOL in the AC/DC module?

Thank you for help,
Marcin

So it seems to me that the the normal of the "conserved flux" as defined by the COMSOL manual is the same on both sides of a boundary for the two PDEs.

Therefore by appropriate scaling of the coefficients of the two PDEs, I can set the boundary condition that I desire.
