[TRNSYS-users] New TRNSYS user question

[keilholz, werner]

Hi John, 

TRNSYS does not come with a FORTRAN compiler; if you want to modify the source code, you have to buy one (or find a free one that suits). More info on FORTRAN compilers can be found at:

http://sel.me.wisc.edu/trnsys/fortran/fortran.htm

The message about converting the .dsp file seems to indicate that you do have a compiler on your computer, but for the Visual C++ language (not FORTRAN).

When using IVF, you can get such a message though; in this case, click 'Yes' and use the 'convert to FORTRAN' function as described in the IVF / Visual Studio manual.

You can also write new TRNSYS types in C++, but not modify existing types written in FORTRAN with the C++ compiler (its not the same language, like if you try to translate from English to French with German-English dictionary ...). 

Hope this helps,

Werner

Hey everyone, 
I'm just getting into TRNSYS for my research, and I'm having a problem.  I'm using the CoGen library, specifically the IC engine, for a model.  I've been trying to edit the source code and I need to compile it with Fortran to get it to update.  My computer doesn't have a Fortran compiler.  
It looks like TRNSYS comes with compilers (CVF66 and IVF91) but when I open CVF this message appears:
---
The project 'TRNDll.dsp' must be converted to the current Visual C++ project format. After it has been converted, you will not be able to edit this project in previous versions of Visual Studio.

Convert and open this project?
---
I click "no to all" because I don't want to do anything I can't undo.  Should I allow this?  Does anyone have a similar experience?
Also, if anyone has a model or demo that actually runs with the IC engine, it would be greatly helpful if you could send it to me. 

Thanks, and have a great day!
John
