The pictures are a start, but I suggest you post your .mph file to the forum. I think that will make it easier for anyone here who wants to help to figure out what is really going on in your model.

SOLVED
The issue was I had to define Dirichlet BC as a Continuity condition at the domains interface.
Without it the second equatuin didn't have any values to calculate.
Best regards,
Oran

Hi Oran,
May I know how did you apply Dirichlet BC as a Continuity condition at the domains interface? A snapshot would be really helpful for me in the comsol setting. I'm doing the similar thing. Hope you help me.
Thanks a lot...

Hi Chaki,
There's 2 options to solve this issue:
1) Define 2 Helmholtz equations within the same component. assuming your variable us , then in the second equation u define Dirichlet BC with prescribed value of . what happens is that it will take the value obatined from the first equation and apply it as continuity. unfortunately I did not use this method so I don't have pictures for you.
2) Using only 1 Helmholtz equation, you can define its parameters as variables. What I did is to define and as a step function that varies in the theoretical boundary, without actualy define a geometric doundary. that solver will handle it.
I hope you will find this helpful

I hope you will find this helpful
