Re: [TRNSYS-users] Existing Model of Horizontal pipe array...?

[David Bradley <bradley@tess-inc.com>]

Francois,
Sorry for the delay in getting back to you. My colleague Jeff Thornton 
has been doing a good bit of modeling of horizontal buiried pipe arrays 
and in so doing has written a few models. I am not sure which of them 
are in the best shape to be distributed but if you can send some 
additional information about the configuration that you are trying to 
model (flow patterns, field characteristics, etc. then I might be able 
to make some suggestions.
kind regards,
David
