    Hi Si Hang,

    The issue comes up again when I tried to get the potenial alone a
    line inside the FEM region. As you have instructed, I uploaded a
    power point file in the Files area (BND.PPT) please take a look.

    Hi Dave,

    Sorry to do it this way, I don't have Si Hang e-mail address to send
    it directly to him. Please delete the file after a few days.

    Thank you

    James

    caused the fast point location routine to break down. It have already
    been fixed.
