Hello,
I made similar simulations with a cylindrical magnet above a metalplate with different relative permeability.
I made a 2D axisymmetric and a 3D simulation with the same geometry and get different results when i made a parametric sweep for the relative permeability from 1..20.
It seems that the 3D simulation has a constat offset with the value calculted from the relative permeability of 1.
I have olso tried to solve the problem but not get a real solution or explanation for the difference.
Maybe this helps a little.
