Hi, I am using ANSYS Electronics to calculate the radial force produced in the air gap for an SR machine. I have set an output variable for the radial force, it is a calculation integrated across an arc in the airgap using the radial and tangential flux densities.

When I go to the intrinsics tab in the expression cache, and attempt to define the integration over all points on the arc, the normalised distance only accepts a single value not a sweep. When trying to select all normalised distances I recieve an error saying it is not supported (using 18.2).

This is causing my results table to come out with zeroes at every point, any ideas? Attached an image, please ask for more details if needed as I am new posting here.
