Have you checked to make sure that all external files referenced in the simulation studio (such as weather files or performance data) have the full file path information?

For example:

rather than

TRNExe will work with relative file paths but TRNOPT does not. This is a rather non-intuitive requirement that is easy to miss.

Subject: [TRNSYS-users] Error with TRNOPT


I am having problem running GenOpt, the error given is as below. I have tried running my system without genopt and it works perfectly fine, but as I ran genopt, the error was given. I cannot find the log file, to determine the error. The error below is copied from genopt.

Can you help me this problem?
