* a line (5um wide) over a plane 100um below
* line length=4000um
*
* Since the line is so long, and the discretization doesn't vary along
*  the line, this is almost a 2D problem by discretization.  But to
*  make it truly 2D, the nodes on the ends of the plane must be
*  shorted together so no current flows perpendicular to the 
*  trace direction.  That is the purpose of all the "np" node definitions.
*  Actually, the line is long enough that we match 2D without shorting them
*  together, but if you really wanted to test against 2D, follow the
*  instructions at the .equiv lines below.
