I have a simple cross section of an electric motor (Switched Reluctance Motor) and would like to count the phase flux linkage. This calculation is done with a "click" in the FEMM program. Can anyone tell you how to specifically calculate this value in Ansys Maxwell?

Obviously, "phase" is a pair of opposite coils where the current at both poles flows in opposite directions.

The author of FEMM - David Meeker wrote to me that Flux linkage is the integral of A*J over the volume of the coil divided by the current carried in the coil. But maybe there is another way to calculate that quantity?

I attach pictures from FEMM where this value is calculated and my section in ANSYS Maxwell. I will be grateful for your help.

You need to use either the Eddy current or Transient solver for tfis.
You can plot the flux linkage with respect to time in the rectangular lot and get the values at each instant for each phase as shown below

Thanks for the answer. Of course, I will also use transient, but first I would like to try to do it "manually" in the magnetostatic. The point is, I want to do all the magnetostatics and the transient is automatically generating the entire power supply for me which I don't want. Besides, I want flux linkage as a function of rotation angle.

Btw do you know whether there is a way to "extract" flux linkage formula from transient?
