Terry,
       here is the part I did not understand the first time around and still
don't understand:

where can I read about the "relaxation thing", this seems to be the crux of
the matter. It seems to be a well known numerical analysis of fields
technique, but I've never taken more that an introductory numerical analysis
class and have not heard of this, and it might be a bit more involved than
you could describe in email...


thanks,
Pete Lawrence.
