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.
Hello,
I hope you're doing well.
I have a question regarding the conversion of an Excel file to a TMY file.
Best regards,
TMY files are text based and each line has to follow a very specific format. There are a number of different versions of the TMY format. All that said, TRNSYS can read various file formats (not just TMx). I would recommend saving your Excel file in either a tab-delimited or comma-delimited text format (both options under Save As...) and then reading the resulting file into TRNSYS using Type9. Solar radiation data will have to be passed from Type9 to a Type16 for processing. There are examples of reading this kind of data file in the .\TrnsysXX\Examples\ directory.
If you want to be a little more ambitious, you can follow the syntax that Type99 uses for "user format" weather data and manipulate your Excel file into that format. It will avoid you having to make connections between Type9 and Type16.
kind regards,
David
