Magnetic Simulation: Simulating Permanent Magnet Separator

[samulon]

I want to simulate a permanet magnets separator. I need to know the attraction force between the magnets and some materials like iron. I don´t know what software i have to use. Thank you for any help.

Here's a thread where I got some suggestions on magnetic field simulation software:

I ended up downloading the evaluation version of QuickField:

It has some pretty good intro/tutorial screen playbacks to get you going. The evaluation version is a bit limited in number of finite elements (256), but should work for you. Several of the other packages mentioned in the thread have evaluation or student versions.

Ok, it may works. Thank you.

I found a problem. The 2D model design doesn´t allow to create a real model. Do you know a 3D program?. Thank you one more time.

Did you check out the other software packages mentioned in the thread?

No i did´t try.
Now I am waiting for a evaluation version of Ansys Multiphysics. As i can read, is the best choice but I am not sure about the magnet forces simulations in 3D. In a days i´ll tell you how it works. Thak you very much for your help.
