surface charge density

Please login with a confirmed email address before reporting spam

Hi everybody,
I'm just starting with Comsol and, although I've simulated some simple models, I have problems placing electric charge in some faces of certain bodies.
The model consist of one cantilever with electric charge at one surface and in front of this face another same sign charge. I have no problems placing the surface charge of the cantilever under a electric potential but I can't solve the problem for two surface charges.
What I have to do? I think this is a very simple model...Can someone help me, please?
Thanks
Miquel
