I agree with most of the comments of you two.
Tesla list and especially some of its members are
trully
frontiers of TC science in World.
Many have done lotta msms,interesting experiments,and
,I dare to say , discoveries as concerns various
aspects of the device.
This particullary holds true for a praxis or as I call
it " 3D problems". 
When I came to TCML , 2 years ago,I was in a search
for a certain specific transient simulation of 
secondary winding,in my naive belif that somebody must
had done it already.
I knew it was complicated  ,but I hopped anyway (hey
1999. -computers were mighty then too!).I was
dissapointed when Terry informed me he hadn't seen
such.
Concerning CW simulation of secondary ,Paul Nicholson
and TSSP project ,have already done a great job with
new and important results.
However ,TSSP  is still  far from being finished since
next step toward the goal, should be time domain
transient simulus IMHO.
After few conversations with people who deal with high
level electrodynamic modelling , agreement about stage
of discretitation etc.,I got a feedback that secondary
resonator above ground plane  can be modeled in terms
of field ( Maxwel) eqs.
Don't need a supercomputer or anything like that for
it,but lotta of  RAM and commercially avilable
processors today (and of course the knowledge of using
softwares like those at www.ansoft-dot-com).

All this is said for the absence of the spark in
processes associated with TC.
When the spark,or nonlinearity appears things are
almost intractible to simul.
Not becouse we don't have hardware/software but
becouse of the absence of complete physical model of
the spark.
Besides,too many known and unknown factors influence
the spark , many experimenters  have noticed that
their coils one day achive one arc lenght another day 
other arc lenght etc.
So,we still have long way  to go before  a definitive
( once and for all) article should be sent and
published.
