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 am writing to you to obtain information regarding type 399. I would like to know if this type works with TRNSYS version 18. I have coupled it with TRNSYS 18, but it does not work. However, it works with TRNSYS 17.
I find that TRNSYS 18 is better for work, so I would like to know how to resolve this compatibility issue with type 399 and TRNSYS 18.
Best regards
Abdel @abdel I do not have any direct experience with Type399. However the following applies generally. The Trnsys17 engine is 32-bit. The default Trnsys18 engine is 64-bit. A Type that is compiled into an external dll (such as Type399) has to be compiled in 32-bit to work with v17 and in 64-bit to work with the standard v18. It would not work to simply use the same Type399 dll with both Trnsys versions.
As a side note there is a 32-bit version of v18 available; you'd need to contact your distributor to get access. Before doing that, I would ask your distributor whether a 64-bit version of Type399 is available. If you are using Transsolar's Type399 then both 32- and 64- bit versions are available.
There are other issues that could cause the behavior you are seeing. The above is just a guess based on a fairly common issue. If the 32/64 bit compatibility issue is not a solution then I'd recommend getting in touch with your distributor for more direct assistance.
