Hi all!
I am completely new Comsol user and I am struggling to deal with the Maxwell equations in H-formulation. I am trying to simulate very simple system which consists of superconductor surrounded by air (insulator) in 2D. I know that it is possible to use built-in module such as ''Magnetic Field Formulation'', however, the goal is to expand the system in the future where the H-formulation has to be used. Therefore, the equations have to be implemented by hand in PDE interface. At the moment I ended up having this equation:
curl(g(H)*curl(H))=partial H/partial t or in other way:
nabla x (g(H)*nabla x H)=partial H/partial t.
here g(H) is a function dependent on H. Other constants I omitted intentionally not to make equation cumbersome. So, I have double curl on the left and I do not how to proceed. I would appreciate any help.
