[TRNSYS-users] Generate radiance file from cmd

[Marion Hiller]

Dear Wirich Freppel,

the call is pretty simple, since the b18 file is the only argument needed:

c:\TRNSYS18\Building\trnRAD\trnRAD.exe  c:\TRNSYS18\Examples\3D_Building\6_Step_Add_Daylight\Building_step6.b18

All parameters for the file generation are included in the "PROPERTIES" section of the b18 file :


*--------------------------------------------------------------------------------
*  P r o p e r t i e s
*--------------------------------------------------------------------------------
PROPERTIES
DENSITY=1.204 : CAPACITY=1.012 : PRESSURE=101325.000 : HVAPOR=2454.0 : SIGMA=2.041e-007 : RTEMP=293.15
*--- convective heat transfer coefficient calculation ---------------------
KFLOORUP=7.2 : EFLOORUP=0.31 : KFLOORDOWN=3.888 : EFLOORDOWN=0.31
KCEILUP=7.2 : ECEILUP=0.31 : KCEILDOWN=3.888 : ECEILDOWN=0.31
KVERTICAL=5.76 : EVERTICAL=0.3
*--- radiance parameters -------------------
SCENE_ROTATION_ANGLE=0 : GROUND_IDS=10004 : GROUND_REFLECTANCE=0.2 : SHADER_REFLECTANCE=0
CALC_MODE=CLASSIC : LATITUDE=48 : LONGITUDE=-9.2 : TIME_ZONE=-15 : SITE_ELEVATION=200
AB=5 : AD=1000 : AS=20 : AR=254 : AA=0.1
LR=6 : ST=0.15 : SJ=1 : LW=0.004 : DJ=0 : DS=0.2 : DR=2 : DP=512


Note: these Parameters aren't included in the TRNBuild dialog window of "PROPERTIES", they are defined in the TRNbuild dialog window "generate radiance files".


Kind regards,

Marion

Betreff: [TRNSYS-users] Generate radiance file from cmd

Dear TRNsys users,

I would like to generate the radiance file from the Windows command window. I know how to do that for the calculation of VFM, by using trnvfm.exe, so I guess the same thing is possible for radiance file generation.
But with trnRAD.exe, it seems to be a little bit more complicated since there are options to set before generating the file, for example, selecting the pre-processing for daylight simulation.

As I would like to generate a "classic" radiance file, could you please give me a hint on the code line to write in order to properly generate the radiance file ?

Thank you in advance
