[TRNSYS-users] Linking MATLAB and TRNSYS

[Arno Dentel]

Ehsan,

 

here is a small m-file example, which change a value in the dck-file
(shift2), saves the dck-file and finally run TRNSYS.

 

 

 

% m file, which calls TRNSYS

%

 

%Test for open an external file and write a value to the file

% Each character uses 8 bits (1 byte)

 

const = 'shift2 = 30';

 

fid = fopen('OneZoneModel.dck', 'r+');

 

fseek(fid, 1102, -1);

fprintf(fid, '%s', const);

 

 

fclose(fid);

 

 

dos('C:\Programme\TRNSYS17\EXE\TRNExe.exe
C:\Programme\Trnsys17\MyProjects\test\callTRNSYS\OneZoneModel.dck /n')

 

 

Freundliche Grüße,
Arno Dentel

Betreff: [TRNSYS-users] Linking MATLAB and TRNSYS

 

Hi,

 

I know that it is possible to call MATLAB from TRNSYS, Using TYPE 155, but
don't know if it is possible to call TRNSYS from MATLAB. What I'm trying to
do is using MATLAB optimization tools to solve a multi-objective
optimization problem. I'm trying to ask MATLAB to read TRNSYS output file,
modify it to create a new input file and initiate TRNSYS. 

Any ideas?





Regards

Ehsan
