    Dear all

    I have a small problem, I think it is discussed before.
    When I calculate the force by line integral of maxwell stress tensor,
    I get four values for it { 0 0 values3 0}
    although I use magnetostatic problems (frequency = 0)
    this "values3" in the table of line integral corresponds to(page 52):
    3 Stress Tensor Force DC r/x force DC y/z force 2x r/x
    force 2x y/z force.

    So, I get "2x r/x force" although I use axisymmetric problems i.e.
    force in z-direction only.

    1- I need an explanations for my problem.
    2- What does 2x force mean? i.e. the required force will be this value
    or divided by 2?

    any explanation is welcomed.

    ahmad
