Re: [femm] force calculation doubt

["Prem Kumar C" <prem@xxxxxxxxxxxxx>]

Hi Shiv,
The assumptions involved in a 2D analysis culminate in a state of invariance
in the z-direction. For example if you are computing the flux crossing-over
some line in your problem, the quauntity you really are computing is flux per
meter depth. If your device has some dimension of "x" meters(x can be greater
than or less than 1.0 mtr) in the depth direction simply multiply the result
by "x". Its as simple as that.

Yeah..The program is really GREAT ...It has nearly all the features
commercial software in this field have. The best part of it is Dave keeps
adding fantastic features every now and then !! Thank you Dave !

Prem Kumar, C
