Jack,
You are on track up to the point of denoting the length. Since you are
exporting from the field solver one would assume that the length was entered
correctly from within this environment. When you export your file from the
field solver you then want to call is as a subcircuit in a line that would
begin with "X" from the main section of your netlist. You also would need
to use a .include line that would call out to the file location.
X1 node_1 node_2....node_n subcktname ~~~> where subcktname is the name of
the subcircuit file you exported from the field solver.
.include "filepath"
You can find these commands listed in your HSPICE manual.

All,
Could someone refresh my memory:
Field solver like Maxwell 2D output into a file that Hspice references
for the
physical description of the stackup and transmission lines???
Then call this file as a lib that you can denote its length??
thanks,
