Seakeeper FAQ list  What restrictions does the Seakeeper Demo
have?  The demonstration version of Seakeeper allows you to open
only the Seakeeper Sample.msd file. Copy and save is not
available  for seakeeping analysis results.   How does the 12
parameter mapping function work?  Q) Could you please explain
the 12 parameter mapping function. I understand the three-
parameter standard Lewis stuff, but what is this (a Frank's
close fit panel method). Can you suggest a reference?  A) The 12
parameter mapping is just like the 3 parameter mapping. Its
still a conformal mapping, but uses more parameters. Its not a
Frank Close fit.  With a 3 (or even 5) param mapping, you can
calculate the mapping parameters directly (the 5 one can use the
area centroids to make more equations to solve -- though we dont
do this in Seakeeper) For the higher order ones, you need to use
an iterative method to find the solution. There are quite a few
papers. See Bishop and Price and also Westlake, Wilson "New
conformal mapping techniques
