motion-induced torque

[phenning@xxxxxxxxxxxxxxxxxxx]

I was curious if there was anything miraculous about the ability to 
compute motion-induced torques etc. using FEA, for example computing 
the torque output of an induction motor at a steady-state slip. 
Several commercial products do this with "rotating airgaps", etc. 
Are these meshing and solution algorithms above and beyond the scope 
of shareware, involving very new ideas, or has it just not been 
gotten around to yet? As a novice I was just wondering.
