Hi,
I wrote a matlab code for heat exchanger, I would like to call the code to TRNSYS , but have problem to setup the code with the mFileErrorCode
Any experts??
Hello, Sometimes the problem is the name of the file (in matlab is not recommended to use "space") or the file path where trnsys is reading the file is not correct including the name of the file. I suggest you to review this. Best luck.
Hello, I think is better to recode your model using FORTRAN and then it's easy to create a new component.
Hi Ali, I have no experience with Fortran, That's why I use the Matlab :D
Some more tips about coupling TRNSYS-MATLAB and calling TRNSYS from MATLAB are listed below.
1. ""STEP by STEP to couple TRNSYS with MATLAB""
Try using type 155 ? Its in \Trnsys17\Studio\Proformas\Utility\Calling External Programs\Matlab and there is even an example in \Trnsys17\Examples\Calling_Matlab
For coupling try the following steps:
1. Update TRNSYS to 17.01( and TESS libraries to 17.1)
2. Go to ".....Trnsys17ExeDLLs", directory
3. Choose archive named by Matlab version you are going to use
4. Place Type155.dll file from archive in the ".....Trnsys17Exe" directory.
5. Make Matlab's "binwin32" folder appear on Windows' search path
If the sample file is run from the same folder where *.m file lays - there is no need to correct path to this file.
-------------------------------------
2. Calling TRNSYS in MATLAB:
mycommand=['!','start',' "TRNSYS"',' /wait /b C:\Trnsys17\Exe\TRNExe.exe',' "C:\Users\.............\NAME OF DECK.dck"',' /n /h'];
eval(mycommand);
)
Hi Ahmed,
"mFileErrorCode" is just a "mark" for you find the place/location of the errors of your Matlab code when calling Trnsys. So, should not bother the "mFileErrorCode".
You can use the same Matlab code, but with "mFileErrorCode=100" or "mFileErrorCode=101". The only difference is that you will get a "mFileErrorCode=???" when encounters error. This is for you to quickly locate the error location.
Best,
hello please if any one can help iam trying to link matlab R2018a with trnsys 16 so that i can perform a mathematical calculation with output from trnsys as input to matlab
these errors always appear
can any one help me to solve them
and how to name the variables in my code so that the trnsys recognize them in there right location in the equation
for example how to link this simple code with tnsys so that Tfeedboiler is the input to code equation from trnsys and output mfsaved ??
and how to write the start commend in matlab to link it with trnsys
