To simulate a permanent magnet separator, the user is seeking software to calculate the attraction force between magnets and materials like iron. They initially downloaded QuickField's evaluation version, which offers limited functionality but useful tutorials. However, they encountered issues with the 2D model design and are now looking for a 3D simulation program. The user is also awaiting an evaluation version of Ansys Multiphysics, which is considered a strong option for 3D magnetic force simulations. Further updates on the software's performance will be provided soon.
