How to set boundaries as continuity ?

Please login with a confirmed email address before reporting spam

I want set the boundary as a continuity but I don't know how?
I know that in Comsol by default the boundaries are define as continuity and it follow this equation: n.j=0
but I want change it to n(j1- j2)=0 (i want the boundary between two domain will be as continuity like n(j1-j2)=0)
how I can do this?

Any help would be appreciated.

Hi

use the geometry assembly mode to define your own contact or continuity equation on common adjacent domain boundaries (that have not been previously grouped by an explicit Union node) check the doc

Good luck
