Welcome to the TRNSYS Users Forum.
The forum is a place where people can interact and have discussions about different topics involving the use of the TRNSYS software package. Here you can post topics for discussion or questions on using TRNSYS and get advice from other users or TRNSYS experts. This forum is not intended for detailed technical support. Users should contact their distributor’s hotline for such assistance.
Some tips for success on using the forum:
- Follow the Forum Rules posted in Forum Administration.
- There are categories for different types of topics and questions. Post your topic or question into the proper category.
- Before posting a topic or question search the existing topics (and the TRNSYS Users listserv archive or Post archive) to see if a similar topic or question has already been answered.
- Use a descriptive topic name. Don’t use attention getting subjects, they don’t get attention and only annoy people.
- State the version of TRNSYS and which add-ons your are using.
- Include enough specific details for your topic of question to be answered. Just posting “Why am I getting an error?” without describing the specific error and what you are trying to do when you get the error will not receive a response that fixes your issue.
- Remember when people help you, they are doing you a favor. Be patient, help people out by posting good descriptions of what you need help with, and be polite even if a response does not solve your issue.
- Moderators may edit your post for clarity or move your topic to a more appropriate category.
From user Alvis Luna:
I would like to ask some questions about TRNOPT. At present, tpf can read type9e data correctly in studio and get simulation results, but when calling TRNOPT, it indicates that type9e can't read data properly. A screenshot is attached.
When a project runs OK when called on its own, but generates a data file read error when called from TRNOpt, the solution is almost always to change the filepath to the data file from a relative filepath (e.g. "datafile.dat") to the absolute filepath to the file (e.g. "C:\\TRNSYS18\MyProjects\Folder\datafile.dat").
GenOpt (the optimization program that TRNOpt wraps around) moves the TRNSYS input files around to run the simulations, which invalidates the relative filepaths. Therefore, all data files used by the simulation need to be specified with their entire path so TRNSYS can locate the files.
