Dear all,

I am currently calculating an intermediate variable using an UDF (the current density j)

I want to find the current "I" at a midplane between two surfaces.

I being the integral of "j", does anyone know how I can calculate it in a UDF? If I do a surface integral it will integrate the current density over all the plane surface, and I only have current densities over a small portion of the plane

Thank you
