I wonder if there is a way to connect TRNSYS and Matlab via COM server.
In the past I was able to connect Matlab with HYSYS using the function "actxserver", in which the the argument of actxserver is the program ID (which is: HYSYS.Application).
I would like to know the TRNSYS "Program ID".
Do you really need a COM Server?
From Matlab and from Python you just execute TRNExe.exe as a subprocess. You just need some scripting to edit ithe input file.
Hope it helps.

Dear Ricardo,
Thank you for your comment.
The initial idea was to create a server and be able to change the parameters, execute TRNExe.exe and extract the results of the simulation directly inside Matlab, just like I did with Hysys. But maybe for this case it should be done differently.
For the moment, I can open TRNExe.exe using the "dos" function. But, I guess, previously the *.dck file should be charged in order to incorporate the desired parameters and then call TRNExe.exe and execute the solver.
Do you have any experience doing that? Or maybe there is an easier way to do what I want to do? Any suggestions will be welcomed.

Victor
Dear Victor,
What you are trying to do is a very common procedure in simulation and I do it on a daily basis. You can do it from a lot of tools. In Matlab, for instance, you can use:
!TRNExe.exe
Or Subprocess is you are using Python (strongly recommended). I recently gave an introductory course on Python Applications for simulation and co-simulation.
There is also an optimizacion program call GenOpt from Berkeley that you can use and download for free. It will be good for you to take a look at the documentation. It can inspire you for further developments.

I have considered this problem. However, I am not allowed to spend much time on it. You may find the following papers useful. Hope I could hear your success.
07. COUPLING TRNSYS AND MATLAB FOR GENETIC ALGORITHM OPTIMIZATION IN SUSTAINABLE BUILDING DESIGN
08. SIMULATION-BASED RECEDING-HORIZON SUPERVISORY CONTROL OF HVAC SYSTEM
-------------------------------------------
FYI. For co-simulation, there is a "Building Controls Virtual Test Bed" by US DOE.

Thank you Junqi.
Although I achieved my goal I will definitely take a look a those papers.

Calling TRNSYS in MATLAB:
mycommand=['!','start',' "TRNSYS"',' /wait /b C:\Trnsys17\Exe\TRNExe.exe',' "C:\Users\.............\NAME OF DECK.dck"',' /n /h'];
eval(mycommand);
