    The program is doing the right thing--the force generated by your
    configuration is just really close to zero.

    Not so.........

    Hi Dave,

    I have attached a Qfield (Ver 3.4, 500 nodes max) screen shot of approx the same
    sim which shows a force of 29.574 N @ -1.497 deg (to the right). Note the flux
    distortion of the magnet's field is also to the right.

    Here in Oz a Newton of force is worth about 100 g of pressure, so if the model
    had a real depth of say, 10 cm we should expect to see about 290 g of force
    pushing the magnet into the horizontal centre of the parallel bars according to
    the Qfield result.

    Actual duplication of the setup in reality does show a good generation of a
    centring force on the magnet.
