[TRNSYS-users] negative value for solar radiation

[David Bradley]

Martina,
   I believe that the error message is being generated by Type56 and that 
"20orientation" means that the solar radiation on the 20th orientation (or 
perhaps on surface number 20) is going out of bounds. Often times this is 
an indication that there is a problem with the incidence angle of solar 
radiation on that surface. For example, there may be solar radiation on a 
surface when the incidence angle says that there should be none. What I 
would suggest you do is to disconnect that particular solar radiation 
connection between your data reader / weather processor and the building 
model and see if you can get your project to run. That may lead you to the 
cause of the error. If not, then I would suggest that you contact your 
distributor to see if they can find the problem in your simulation. If you 
aren't sure who to contact, please send me your user id number (found in 
the file user16.id) and I can put you in contact with the proper person.
Kind regards,
  David
