    Hello again, I am here with new problem.
    Remember that two paralel strips problem, inductance?
    now i consider AC current, so I just put 50Hz instead of 0 in
    Problem definition dialog box. Also I put "Pure Iron" instead
    of air but I changed mi0 so it is not pure iron exactly.
    But, this is irelevant in my problem. The point is that when
    I put 50 Hz current in copper i get picture of magnetic flux
    with lines of flux close to copper. it is ok picture for linear B-H
    curve. now, if I put non-linear B-H curve I should get lines
    of magnetic flux (contours) that are more spread ower iron.
    (B=u*H, so if I change B/H ratio in curve I also change u?)
    u = permeabillity
    of course "working point" of my model should be behind the "knee"
    of curve ?
    with what values in my model can I achieve that?
    thanx
    tomislav
