I am a student who is using the Ansys Electronics Desktop Student Version to model a 3-phase transformer. The solver that I am currently using is eddy current.
As shown in the animation below, the magnetic flux density of a plane that I selected changes along the phase.
However, when I used the field calculator to calculate its magnetic flux and then created a report of it along the phase, I got a result as shown below. As you can see, the magnetic flux does not change along phase (although the flux seems to change in the report, the flux value of the apparent minimum and maximum points on the curve are in fact the same. And the reason for this wired thing is also my question.) This means the magnetic flux of that plane is constant, but there is a conflict between this conclusion and the animation it shows me before.
The calculated flux and the report I got are obviously wrong. I want to know the reason why I got this incorrect result. Is the expression of the magnetic flux in the field calculator wrong? And how I can get the correct one?
Thank you so much!

The main reason why you get almost constant results in the rectangular plot is because you are integrating the B field over a surface. But in the animation, you can see the MagB field quantity in each “point” of the surface.
If you want to see the same as the animation, I suggest using a point or small line and plot (rectangular plot) the B field there. In your case, you are interested in knowing the B field variation at different locations. Then you can use several points or create a line that crosses the surface from one extreme to another. Ivonne
