[Getdp] Torque and force calculation based on Virtual Work prinzip

[Mang Cai]

Dear sir,

I have analyse the machine_magstadyn_a.pro file of the electrical machines library of the onelab project carefully and found that the electromagnetic force and torque calculation based on the maxwell tensor is implemented. But that based on Virtual Work is only partly implemented, during the postprocessing phase, the Kern function of VirtualWork[{d a}] is unfortunately does not exist.

Can someone give me some advices to complete this work?
Because it should be very useful to compare the force and torque calculated through the two different approaches.

Thank you very much.
