In general, I'd like to recommend to open the file at least once in FEFLOW 6 Classic - the old-style interface. There you'll see all the properties for unsaturated flow directly in the equations. The input (and naming) in FEFLOW 6 Standard will be done more convenient in version 6.1.
The fitting exponent in relative conductivity curve is not used for the VG Modified model, thus it has no meaning at all.
