Re: [TRNSYS-users] long wave radiation

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

Ahmed,
  By changing PAR(2) you are eliminating certain zones from the
radiation balance. Since the input file doesn't run with 100 or 99, I
think that means that the problem is occurring in one of the first two
zones. Once you eliminate those from the radiation balance (by changing
the value to 98) the simulation runs again. I don't know exactly what the
problem might be... I would suggest that you contact your distributor and
have them look at the .bui file to see if they can determine the cause of
the problem. If you aren't sure who to contact, please send me your
registration number (16-Yxxxx) where Y is a letter and xxxx is a number
and I can give you the correct contact information.
Kind regards,
 David
