Hi everyone! Recently im using comsol to model an induction machine in 2D. The machine is supposed to be fed with voltage source. First i use global equations to calculate the stator phase currents, then the results are divided by the area hence the current density is derived. However when i feed the stator with this current density and run the machine in a transient mode an error came out saying that 'nonlinear solver didnt converge. Maximum number of Newton iterations reached. Last time isnt converged'. I guess something went wrong with the global equation on current density calculation? Can you guys help me? thank you!
