Nonlinear electric conductivity
Hi, I'm currently working on electrical transients simulation using AC/DC module. How can I define nonlinear electric conductivity of zinc oxide (ZnO) in subdomain settings? Thank you

Hi what kind of non-linratiry ? if its a dependence on T or J or B, it is "just" to do as many material characteristics of the Material library, find one in the defult Material library and copy the...

First of all you should get an expression (or experimental data) for the conductivity. If the conductivity depends on J or even B, you might run into a "circular reference" problem. Then you need to...

Its dependence is sigma(E), where sigma is conductivity of ZnO (S/m), E - electric field strength (V/m). This conductivity is non-linear and usually should be set manually using table. Is it possible...
