Singularity error while solving an Induction machine

Please login with a confirmed email address before reporting spam

Hi,

I am trying to model a Induction machine in COMSOL. What I have observed is that as soon as I provide any rotation to my rotor, I am not able to solve it. It gives me singularity error. However if I keep rotor speed to zero, the simulation runs quite fine. Can any one please suggest what could be the problem?

Thank you,

Gaurav
