Hello everyone! I am trying to develop Doubly-Fed Induction Generator model in Comsol. To be able to take into account the end-winding effect of the stator and rotor windings, I faced with problem, how to connect field domain with electric circuit model in Comsol. For the coil modeling I am going to use Multi-turn coil node. Because coils should be voltage excited, the best way is to use (External U vs I feature) interface in electric circuit. The description of using U vs I in Comsol manual is very weak.  When I am trying to solve the model, I do not have current in my coil at all, or sometime error message generated.

For the simplicity I uploaded very simple example, of one coil. Could someone please suggest how to connect field and circuit correctly in my case? Thank you very much!
