[TRNSYS-users] ddl or api for trnsys.exe

[Maurice Charbit - OZE-ENERGIES]

David

What you advise is what I did:
    arg1                   = directory where TRNSYS.exe is
    arg2                   = name of the DCK file
    arg3                   = "/h" (to avoid that window open the interface)
    exe_trnsys        = subprocess.call([arg1,arg2,arg3])

but it is very slow. A better way will be to have a .dll

best regards

Maurice,

 I have not used Python, however, TRNSYS can be called from the command line so I assume it would be able to be called from Python as well. The command line to run one of the TRNSYS examples is:



c:\Trnsys18\Exe\TRNExe64.exe "c:\Trnsys18\Examples\Calling_Contam\CombinedThermalAirflow_AHU.dck"


if you add a /n at the end of the line then there will be no need to click "ok" when the run completes.

if you add a /h at the end of the line then TRNSYS will run entirely in the background.


kind regards,

 David

Hi,

I am using TRNSYS for industrial development.  For this purposes  I develop a program in Python language which calsl TRNSYS.exe via subprocess function. It takes a lot of time because it means running via Windows.

Does it exist  a code (something like an API or a DLL)  which can be called directly from Python ?

Best regards



Maurice
