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



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

Dear Trnsys users,

I recently had the following error : Error 24
"The size of the array which holds the operation codes for EQUATIONs and CONSTANTs in the TRNSYS input file has been exceeded.  Try reducing the use of EQUATIONs and CONSTANTs in your input file if possible or increase the limit on the maximum number of equations that TRNSYS allows."

I know that Trnsys allows only 999 equations/constants per simulation, but in my case I don't exceed this number.
Does anyone can tell me more about this error, because I don"t understand the reason of the problem ?

I managed to go round this error by splitting my .*tpf in two and calling the results of my first simulation with a data reader type, but it is not very convenient.

Best regards,

Ewen Raballand
