Hello TRNSYS users,
Here is my problem: I am preparing a parametric analysis on a simple Type 56 building zone model with one of the parameters being the window-to-wall ratio.
Using a script I can easily convert the desired window-to-wall ratio in window/wall areas and coordinates, and modify the corresponding surface coordinates and areas within the .b17 file. But then it is necessary to re-generate the complete set of shading, insolation and view factor matrices, and I would like to do it without having to open TRNBUILD and manually click on "generate matrix".
I've already managed to re-generate the View Factor matrix calling the TRNVFM program from the command line, but as for the Shading and Insolation matrices there doesn't seem to be a straightforward solution. In the Type 56 manual it is said on page 95 that "TRNBuild calls an auxiliary tool based on TRNSHD" to generate these matrices, but unfortunately this tool seems to only exist in the form of a dll ("trnshdbui.dll" found in TRNSYS17\Building directory). Is there a way to generate the Shading and Insolation matrices from the command line?? Would it be possible to get the TRNSHD prpgram in an exe format?
Thanks in advance for your help.
Best regards,
