Hi and happy new year!
I have a problem with running a two-phase grid-based irradiance simulation. I am a begginer user of it and I started with the tutorial from @sarith, which I managed, but when I switch to my own model I have some issues.
My problem is that my result is fluctuating a lot and the simulation runs suspiciously fast (a few seconds for an annual simulation), so I think that something goes wrong with it. I thought it was an issue with my simulation parameters so I started increasing ab, ad, as and decreasing lw. I am using now these parameters: -ab 6 -ad 16384 -as 16384 -ar 128 -aa 0.05 -lw 6e-5, but still the simulation runs too fast and my result fluctuates a lot.
The commands that I am running are the following:
*rfluxmtx -I+ -y 2 -ab 6 -ad 16384 -as 16384 -ar 128 -aa 0.05 -lw 6e-5 -n 4 - skyglow.rad -i RadSimu_blue_9_oct.oct < RadSimu_blue_9_0.pts > RadSimu_blue_9_illum.mtx *
## Run gendaymtx and dctimestep separately for sun and sky (I want to use a colored sky)
gendaymtx -m 1 -d CHE_Geneva.wea > RadSimu_blue_9_sun.mtx
gendaymtx -m 1 -s -c 0.644 0.884 0.963 CHE_Geneva.wea > RadSimu_blue_9_sky.mtx
dctimestep RadSimu_blue_9_illum.mtx RadSimu_blue_9_sun.mtx > RadSimu_blue_9_annual_sun.ill
dctimestep RadSimu_blue_9_illum.mtx RadSimu_blue_9_sky.mtx > RadSimu_blue_9_annual_sky.ill
From these, I get the 3 channel results which then I use to calculate alpha-opic weighted values (from CIE S 026).
Can someone help me figure out what goes wrong? Here are my simulation files.
Thanks!
Kind regards,
Myrta
