Not quite.  The above predefined voltage distributions are used
to obtain a quick estimate of Ces in the compute_Ces() function
of geotc.  But when you call the compute_F() function, it will
determine the actual voltage and current distributions, taking into
account all the component objects you've specified.  The G.PROFILE
that you specified when installing the secondary is ignored when
this function is called.

Geotc uses eqs 6.3 and 6.4 from

  http://www.abelian.demon.co.uk/tssp/pn2511.html

to determine Fres and the voltage and current distributions,
given the capacitance matrix (as described in another post), and
an inductance matrix.  This enables all the work to be done
without using any complex numbers.
