Dirichlet boundary not working

Please login with a confirmed email address before reporting spam

I add a Dirichlet boundary at the interface of two coefficient form PDE whose indepedent vairables are p and u,v, respectively. I want to have a boundary condition of p=alpha*u+beta*v, for example. So I add a Dirichlet boundary condition in first PDE denoting the formula alpha*u+beta*v. However, the results show this condition is not working because the contour shows the value of p and alpha*u+beta*v are not the same at very near to the interface. Is there any wrong in my model?

This sounds like a great opportunity for you to post your a .mph file to the forum, so that readers here can see exactly what you did, and then -- very possibly -- can help identify what went wrong.
