Re: [femm] Solenoid Model

["sihang" <stsc_sh@xxxxxxxx>]

Hello Mike,

   I also get the same force value in femm(a bit more larger than you got). I checked it in Ansys that found the result in document was calculated with a convergence tol 1e-3, which in FEMM, solver's default convergence tol is 1e-8.
So I resolved the model with a  convergence tol 1e-8, the force I got was changed to -5.76N.  There hardly to say which result is more accurate on this model.
