Magnetic Modeling
(OP)
Does anyone know of a magnetic modeling software? I am trying to use the strength of one magnet to move two other magnets quite a distance (seperated by 6061-T6 casing) from it. I would like to model this magnetic coupling.

Another software is called "maxwell". good luck.

It has a good magnetic part...

femm is free
I haven't used it but I hear it is OK

The preprocessor allows the user to draw parts, specify materials, and so on. DXF drawings can be imported into the preprocessor.
For mesh generation, triangle is employed to create a constrained Delaunay triangulation.
The solver addresses 2-D planar and axisymmetric magnetic problems (including linear and nonlinear magnetostatic problems and linear low frequency harmonic problems). For magnetostatic problems, a Conjugate Gradient solver using a Symmetric Successive Over-Relaxation (SSOR) preconditioner is employed. For harmonic problems, a complex-symmetric implementation of the BiConjugate Gradient algorithm is used, again with the SSOR preconditioner.
The graphical postprocessor allows the user to examine and manipulate the solution. The contour and density plot renderings of the solutions are available. Plotting of various field quantities along user-specified coutours is supported. A number of integrals along user-defined contours and areas are also supported.
A powerful scripting language, Lua, is integrated with the program. The scripting language allows for batch runs, creation of animations, dynamic simulations, and so on.
There is no hard limit on problem size--maximum problem size is limited by the amount of available memory.

ANSYS is very very good, has very complete fascilities (libraries), but it is very complicated. For example, it has more than 150 element types. It is almost not like a tool, because everything should be defined by user. So, it is not a user-friendly software. It has also poor fascilities in drawing.
Maxwell is user-friendly software. Many people use this software to analysis, for their project and research.
FEMM is easy to use, simple and free. It can be used to simulate 2D static for electromagnetic and electrostatic problem. Latest version (V4) is under development.
Another useful fascility is macro. Both Maxwel and FEMM have a better macro facility.
