Dear Pauline, In Trnsys3D you can
define shader surfaces and heat transfer surfaces like walls windows etc. After finishing the drawing
there are two ways to continue: -
Import the IDf file directly into Studio by the 3D building wizard. -
You start TRNbuild and use the Import function. This creates you a
B17 file only Shading matrices are created by TRNbuild only. For creating a shading
matrix you may check documentation 05-MultizoneBuilding.pdf section 5.2.7, 5.2.7.2 and 5.5.1 The matrix files don’t exist in the studio. They are assumed
to be in the same directory as B17 file and have a fixed name. Type 56 uses the shading matrix automatically when it is there. Check
for a notice in the list file. Concerning the capacity, do
you use the latest TRNSYS 17.00.0019? This should work fine. V1....Vx means 1st,
2nd, ....Vertex ID Regards, Dipl.-Ing.

[mailto:p.gelin@katene.fr] Dear all, I would like to know when and where the new shading matrix file is used
in TRNSYS simulation studio. I drew a building with a shading object thanks to the Sketchup plugin
TRnSYS3D. I imported it in TRNBuild and I could read information about this
shading object in the window “Geo-Info”. But I don’t know what these parameters (from V1 to V4)mean and
above all where they are use. I read on the MultizoneBuilding manual that a .shm file was also
created. So I thought it was like a .dat file and should be linked in the
simulation studio but I didn’t find where. Is there anyone who knows when and where the shading datas are used
during the simulation? I have also another little question, always about the IDF file import
in TRNBuild: volumes of zones are well imported but the linked capacitance
calculations are not done. Is there a problem from my file or is it always like
this? Do I have to multiply by 1.2 myself manually? Thanks a lot in advance. Pauline Gelin Katene Engineer, fluid design office. |
