Re: [TRNSYS-users] TRNSYS error 300



Carlos,
 I have been getting this error too. My first "fix" was to change the error message to say that it may be a problem with either Type66 or Type56. Not much of a fix at all.

 I think the cause of the error is that when running from Studio and TRNEdit, TRNBuild gets called to process the *.b17 file and generate the *.bld, *.trn, and *.inf files. When called from TRNSED, however, the call to TRNBuild is bypassed and Type56 uses existing (already processed) *.bld, *.trn, and *.inf files. I managed to avoid the error by changing the "error" to a "warning" in my version of callProgram. This is just a workaround for TRNSED though; we are currently working on a permanent solution with Transsolar.
Kind regards,
 David

Dear all,
 
Whenever I ry to run a type 56 simulation in TRNSED I am given the following error even though the same program runned perfectly in TRNEdit
 
 ***** ERROR *****        TRNSYS ERROR # 300
 UNABLE TO START PROGRAM IN CALLPROGRAM UTILITY
 PLEASE CHECK PATH AND PROGRAM NAME, THIS MAY BE A PROBLEM IN TYPE 66

    TRNSYS Message    300 : The TRNSYS Program attempted to evaluate an EQUATION that raised a negative number to a non-integer value. Please check the EQUATION formulation and re-run the simulation
    Reported information  : Not available
 
the message is not very helpfull and I don't even use Type 66 in my simulation and I checked all my equations and nothing obvious comes to view.
 
Is there any known solution to this problem? If need be I can send you the files im using.
 
Thank you
