[Radiance-general] gensky sky type

[Wendelin.Sprenger at ise.fraunhofer.de]

Dear JH,

at the moment, every feedback for errors of gendaylit is especially 
appreciated. 
We are currently adding some new features to gendaylit especially to avoid 
errors for surise/sunset. All new features of gendaylit will be presented 
also during the radiance workshop and we hope to have the new release 2.2 
ready before the RADIANCE workshop takes place. 
However, the error you have mentioned might be a different one. We are 
just working on some bugs of the -L option. Are you using this option? 
Please specify the precise command that leads to the error, including the 
precise error message and your version of gendaylit (just type gendaylit 
in your terminal). 

Wendelin

Hi all, 

I am using gendaylit with input from weather file. During sunrise and 
sunset, gendaylit shows "ERROR: Model parameters out of range".   so I 
plan to use gensky to generate the sky model (-B b -R r), where b and r 
are calculated by "illumiance/179". However,  I found the illuminance 
value at 5 pm (calculated using gensky with default sky type) jumps a lot 
from illum at 4 pm (calculated using gendaylit). I changed the sky type to 
+i, which decreases values.  My question is that how I should choose the 
sky type for gensky to avoid big change from gendaylit? 

Thanks 

JH
