torque computation

Dear all,



I have some problems calculating torque of an induction motor. When i'm
doing a harmonic analisys, femm doesn't take into account B-H curve and i
put a linear mu, but i can't achieve a valid result. i'm simulating a
quarter of the motor but if i rise up mu, induction is huge. Do you have any
clue to solve problem?

i'm calculating torque from stress maxwell's tensor across a centered curve
round the airgap with a fine mesh in it.



Thank you



Diego Pérez
