[TRNSYS-users] parametric study in buildings

[hotline]

Hey,

Batch programming is a programming paradigm that allows automated execution of certain commands at the level of an operating system. A batch file is a "batch" of such commands. If it is called with the command line, the system executes each individual task listed there one after the other. That's why the term batch processing is common.

Here is an super simple example of a batch file which calls a Trnsys template:

  *   open an editor and type in the following line: c:\TRNSYS18\TrnEXE64.exe c:\TRNSYS18\Examples\3D_Building\6_Step_Add_Daylight\Building.dck
  *   save as *.bat
  *   double click on the *.bat file an the simulation should start

When you want to run several simulations in series or parallel you can add it into this batch file. Please have a look in further literature.

best,
Christoph

Dear Christoph,



Thanks for your answer. I needed a confirmation for that.



But, may you please, explain to me what is a batch and how to run it?



Thanks in advance,



Oussama

Dear all,



Unfortunately there is no such possibility to do this in the Trnsys17 environment automatically. In my understanding the easiest way for you, is to create a number of  .bui files with different window areas (Yossef already described it - thx for that) and then run it with a batch.



Best,

Christoph

I think that if you are looking to modify the WWR, you have to modify the window AND the wall areas in order to get the same total area as before the modification.

It's possible in TRNSYS 17 by modifying the .b17 file manually or with a script (matlab, python...).

Hello every one,



I am trying to perform parametric study in buildings, where one of the parameters is the windows to wall ratio (WWR). I am defining the area of the walls and I intend to change the area of windows, thus, the area of the window is the parameter under consideration.



Does anyone have an idea if this possible using Trnsys17.



Thanks in advance,



Oussama
