Error coupling FEM electric generator with EC Load

Please login with a confirmed email address before reporting spam

Hello,

I am currently simulating a permanent magnets generator with load and i am getting an error. I want to use the physic rmm to prescribe a rotational velocity in the rotor and then the physics ec to simulate the load of the generator as concentred paramenters. When i put an multi-turn coil connected to an resistance the comsol is able to simulate the problem. However when i put as load an resistance in series with an inductor the comsol give me an error:

" Failed to find consistent initial values.
Last time step is not converged.
- Feature: Time-Dependent Solver 1 (sol1/t1)"

Anyone can help me to solve this problem?

Thank you!
