`
To Dear Tomislav:`
`How are you? Did you get inductance, L(femm)=1.1517 e-6 H/m, with your
FEM model? I did not. At a glance, there is no space, left of left conductor and right of right conductor, and top and bottom too. In other words, there is no room for filed to develop fully. Or, the text file attached was corrupted in the delivery via e-mail ?`

    Thanks
    Sincerely,
    SE-HO YOU
