Re: [TRNSYS-users] Calling TRNSYS from Matlab

[Marcus <jones.0bj3@gmail.com>]

You can achieve this by scripting each step of your process in Matlab. I have done this in the past where I did a simple string find / replace on a copy of a template DCK file to update values, and then executed the simulation from the command line. Something like dos("TRNEXE template1.dck"). I had a conference paper last year which has an overview of the coupling; http://www.optimalenergetics.com/Blog/?page_id=7, and since then I've moved everything into Python where I can take advantage of object oriented programming, demo of this is here if your interested; http://www.optimalenergetics.com/Blog/?p=78

Cheers,

Marcus

Hello All,

I am trying to implement a code with the following basic information flow:

1. Matlab generates a set of system parameters.
2. Matlab passes those system parameters as inputs to TRNSYS.
3. TRNSYS runs a year-long simulation using those system parameters and supplies the results to Matlab.
4. Matlab uses the results to determine a new set of input parameters.
5. Return to Step 2 until some exit condition is reached.

I've looked at the documentation for Type 155, but it appears that it is used for calling Matlab while running a TRNSYS simulation. What I'm looking for is a means of calling TRNSYS from within Matlab and running repeated simulations. Any help is appreciated.

Thanks,

Josh
