Comsol 4.0 : electric currents - el. potential V continuity between two...
Hello all, I have a fairly simple yet bizarre problem with my Comsol model. I am using Comsol 4.0, 2D, Electric Currents. I have an annulus (a ring) that's split in two domains, each with a different...

Hi, actually I would expect the COMSOL result and not your analytical calculation. The potential is obviously continuous at the internal boundary, but with a kink,which is to be expected, because the...

Dear Edgar, Thank you for your reply. However, I can not agree with you on this matter, considering the following: - the conductivity, as its constant in regards to space and time (does not depend on...

But the conductivity is different in the two domains, so it is dependent on a spatial coordinate. A simple analogy would be a serial circuit of 2 resistors. Say you have 1 Ohm and 9 Ohm in series and...

Your equation iv should read iv) J_domain1 (r = r_med ) = J_domain2 ( r = r_med) not iv) E_domain1 (r = r_med ) = E_domain2 ( r = r_med) Jeff
