>> Dear list,
>>
>> I was trying gendaymtx and the new dctimestep (it works excelent, thanks
>> to the developers), and noticed the following.
>>
>> I modeled a big cube, and set sensors pointing north, south, east and
>> west (the idea is that the cubes shades). Then, I made a DC matrix, created
>> the sky matrix; and dctimesteped all together (the weather used is
>> Montreal), and got THESE<https://sites.google.com/site/sunliteproject/comments>results.
>>
>> The sensors were defined (North, South, East and West, respectively)
>>
>> 0 3.1 1 0 1 0
>> 0 -3.1 1 0 -1 0
>> 3.1 0 1 1 0 0
>> -3.1 0 1 -1 0 0
>>
>> Anyway; North and South seem to be ok to me (simetric along the day, and
>> the south has more "sun" than north). But West and East seem to be
>> inverted...? and the east is more insolated in the afternoon? (I havent
>> really looked at the numbers themselves, but just to the tendency). *Can
>> there be a bug in the program??*
>>
>> On the other hand... is there any plan on adding the -O option to
>> gendaymtx, to get the solar intensities?
>>
>> THANKS TO EVERYONE IN ADVANCE
