Yes,  If you know your terminal voltage you can input that and then the
E-fields will be accurate in relation to the coil size.  It outputs the
real voltage on the grid.  You may have to divide that number by the room
size to get the true volts/meter.  I will look into that...

I simply fine the voltage "difference" between grid points from the above.

The Soutput.xls file shows high field stress points.  You need to look at
that and try to minimize the stress at the top winding of the secondary.  A
toroid tends to arc a little above its centerline on the outside in any case.
