David,<br>We were working with different versions of trnsys 17.00.0016 and 17.00.0019. I recently upgraded my trnsys and the problem doesn't exist any more. If you still want to have a look at the input file I can send it to you. Thank you for your help.<br>

Ewen,<br>
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.<br>
Best,<br>

<br>
I recently had the following error : Error 24<br>
<i>"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><br>
<br>
I know that Trnsys allows only 999 equations/constants per
simulation, but in my case I don't exceed this number. <br>
Does anyone can tell me more about this error, because I don"t
understand the reason of the problem ? <br>
<br>
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.<br>
<br>
Best regards,<br>
