Re: [TRNSYS-users] Features of TRNSYS 17

David,

Glad to hear the improvement TRNYS 17 will bring over the previous Version 16. In addition to features you mentioned, I think the following should also be addressed by the development team:

1. Improved debugging. TRNSYS is “well known” for letting users to guess what actually the error messages it displays mean. I started using TRNSYS 15 and then converted to TRNSYS 16. I believe, TRNSYS 15 debugging is better (read: straightforward) than TRNSYS 16.

2. Direct translation of user defined TYPES / subroutine from previous version 16 to 17. If this is not addressed, the users like me will again get frustrated and spend a lot of time to transfer their project from previous version to version 17. Creating the skeleton using “Export as Fortran / C++ ….” is not enough. Using this skeleton, users still spend a lot of time to copy paste the codes, checking the syntax and or defining variables …

3. You wrote: “The user will probably have to adjust the way that they structure information in TRNBuild”. I do not know whether this also means: we are not able to actually run directly the previous TRNBUILD file in version 17?

4. Get rid of notorious “Error message 1000”

5. Optimised ordering of TRNSYS Simulation studio components without the user needing to do manual ordering.

I may have some more “wishes” later on, but for the time being I encourage users like me to send their wishes for TRNSYS 17 in this forum.

Thanks, Marcello, for reminding us about this.

Regards,

E Halawa

Marcello,
You are correct that a new version is planned for release in summer 2009. The major new features of version 17 will center on the building model. Specifically, TRNSYS will do a much better job of handling building self shading and internal solar radiation distribution through the use of a graphical preprocessor. The details are not yet fully worked out but in the current testing, the user draws the building in Google SketchUp, then exports it to TRNBuild through the use of a preprocessor). The user will probably have to adjust the way that they structure information in TRNBuild. The use of the preprocessor itself is quite straightforward and the structure of the TRNSYS Studio will not change substantially. One important new feature there is planned to be a two-tab view of the input file (*.dck and *.tpf). Another new feature will be a very flexible component that will calculate energy transfer between a building and the ground. There will be a number of other new features and models as well but these three are the most significant developments.
Kind regards,
David

Hy!

I’ve read in a previous message that a new release of TRNSYS is planned for the next year.

I wonder if TRNSYS 17 will include widespread changes in the interface and in the models with respect to the present version or it will be just an “adjusted” version of it. Do you have already defined which are the main new features?

Thank you!

Best regards,

Marcello
