Electric potential boundary on thin structure

Hi!

My model contains a thin film with a thickness of 30 nm. I have applied different potentials and grounds on the thin boundaries of this film without any problems, but now I'm trying to apply these two boundary conditions on one of the flat sides of the film and the resulting potential doesn't turn out the way it should.

Is there a way to get a proper result by using these bc's on the flat side or do I have to stick with my old solution (i.e. potentials on the thin boundaries)? I made a quick model to illustrate my problem. thick.png shows what I would like to get (here I've increased the thickness to 30 µm) and thin.png shows the unwanted result due to the thinness of the geometry.

Thanks.

Hi,

have you considered the distributed impedance BC?

Cheers

It seems to do the trick. Much appreciated!
