thanks Riccardo for your reply and your help.
Unfortunately I have already set all the mFileErrorCode like your suggestion but I still have the same error.
It would be an issue with a too recent version of Matlab? (I’m using a 64-bit version of Trnsys 18 (18.00.0016) with a 64-bit version of Matlab 2016a)

Hi elisa
you have to put "mFileErrorCode=some_number" in the m.file to get the point when your script fails and you MUST write "mFileErrorCode=0" at the end of the m.file.
you have to write
"mFileErrorCode=0
return
"
also at the end of some particular "if statment" like:
if trnInfo(8)==-1
...
...
...
mFileErrorCode=0
return

Oggetto: [TRNSYS-users] type 155 and GenOpt
Hi TRNSYS users,
I’m trying to run an optimization with TrnOpt with a link with matlab (type 155). The single simulation works, but when I run the optimization I have always the same error: “The M-File did not properly set 'mFileErrorCode' to 0 when it was called. This may indicate that an error occurred in Matlab while running the M-File. 'mFileErrorCode' was left to 1 by the M-File. You can set ignoreEngineClose to 1 and run the 'lasterr' command in Matlab to help diagnose the problem. The error occurred at info(7) = 0 , info(13) = 0”.
I think it’s a problem with matlab file access because , despite the .m file being inserted into the GenOpt input file, the GenOpt seems unable to start it, in fact GenOpt starts matlab but then fails to open the file.
Someone of you has already dealt with this issue?
Kind regards,
