Specifying Internal Boundary

Please login with a confirmed email address before reporting spam

I have a 2D problem with 2 variables. The rectangular domain is divided into 2 subdomains with 2 variables defined uniformly ie u1 and u2 in each of it. I need to define the internal boundary by coupling variables from both subdomains , ie u1 of subdomain1 and u1 of subdomain2 are be used in the boundary condition. I can not use expession like u1a- u1b as u1 is used in both subdomains.

Is there any way to specify this boundary condition?
