[TRNSYS-users] Error 24 : array size of equations

[David BRADLEY]

Ewen,
   By default, TRNSYS (v17) allows 2000 equations. I believe that TRNSYS 
16 allowed 1000. However, the error you are getting is not that there 
are too many equations/constants but that there are too many operators 
in your equations! That is not an error I have ever gotten! Impressive! 
The two are related; the number of allowable operators is set as a 
function of the number of allowable equations. Your distributor should 
be able to provide you with a TRNDll that is compiled to allow more 
equations but I would appreciate it if you would be willing to send me 
the input file that generates the error so that I can have a look as well.
Best,
  David
