Hi,

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

Hi

which kind of non linearity ? material properties depending on T, or V or I or B-H ? I would say, addthe corresponding a material property as an interpolated function, and be sure your variables are defined and solved for, then it should be "automatic"

Good luck

You can check out the Inductive Heating example in the COMSOL Model Gallery (Model ID 148: www.comsol.com/showroom/gallery/148/). It has a nonlinear electrical conductivity.
