Integral over a disk in different positions

Hi!
I have computed a magnetic field in a region of space and have defined a disk inside that region.
I would like to compute the energy in the disk, which involves integrating the magnetic field, for different positions and orientations of the disk in the region. For this, I don't want to recalculate the magnetic field before each integral, as it does not change. I would like to compute the magnetic field just once and then create a parametric sweep that changes the position and orientation of the disk and calculates the integrals. Is there a way to do so?
Thanks in advance for your answers.
Alberto.

Hello Alberto,
You can do what you want by using the general approach presented in this blog (You'll use it to evaluate an integral rather than a maximum):
www.comsol.com/blogs/maximum-evaluations-on-parallel-sections/
You'll want to use a boolean expression in the integrand to restrict the integral to a finite disc instead of a full plane.
Best,
Jeff
