A list of the best free magnetic-field, simulators

[guest1289]

I thought maybe someone should start a list of the  best  free  magnetic-field,  simulators ,  just so people might have a less important alternative way to test  magnet-motor  designs  etc,  obviously it is not a satisfactory replacement for building actual devices .

   (  Personally I'm only interested in the fields of  permanent-magnets,  but I would hate exclude  simulators of the fields of electromagnets from this thread  )

   (  I think that these types of software would be very limited or ineffective when it comes to eddy-currents,  but what about magnetic-fields interacting with each other,  and in particular magnetic-fields interacting with each other from a long distance,  so that two fields might only interact in an undulating or intermittent manner   )

    Which are the best  totally  free  magnetic-field  simulators

There are several open source packages that have solvers for magnetostatics.
1. MaxFEM (MaxFEM)
2. ELMER (Elmer finite element software)
3. OpenFOAM (Standard Solvers -- included the static magnetic solver)

one i tried was this: http://www.femm.info/wiki/HomePage
its free enough. and with the right amount of LSD, you WILL discover overunity using this useful software!
LSD is probably not needed, just download the software from that link and find yourself lost in it for hours trying out different settings.

ideally it would have templates of other inclusions, such as different materials, shapes and numbers of materials etc.

  I'm   guest1289,  this is my other account,   for other things I'm doing  .

   thanks for those

   Since I won't be able to build any of my designs, this software is better than nothing

Thanks for update....

Thanks for sharing this list of the best free magnetic-field. This is really very useful information.
