Calculation of the radial force of the rotor of a motor

Postby Jenwel » 12 Jul 2017, 10:17

Hi,
I am anlyzing the force acting on a rotor of the switched reluctance motor in a 2D transient model.
The solver "MagnetoDynamics2D" is used to solve the potential, and the "MagnetoDynamicsCalcFields" is used to extract the distribution of flux density, and also the magnetic torque and force acting on the rotor.
I find the nodal force are saved in the vtu results. But I want to know how to calculate the scalar radial force in X and Y direction acting on the rotor, and save them in the .dat file?
I know the force acting on the rotor may be summed, but I do not know how to call the related variables in Elmer.
The sif and mesh files are attached.

Thank you in advance!

Best Regards
Jenwel
