    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 !
