Hi all,
I'm trying to automate the calculation of illuminance values inside an
office, during 4 different days of each month of the year. I've saved
the script below as venezia.csh and then I've written chmod u+x
venezia.csh, and finally ./venezia.csh.
#! /bin/csh
set opzioni = (-ab 7 -aa .1 -ad 2048 -as 1024 -ar 512)
foreach mo (1 2 3 4 5 6 7 8 9 10 11 12)
foreach da (7 14 21 28)
foreach hh (4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21)
gensky -a 45.50 -o -12.33 -m -15 $mo":"$da":"$hh -u -g 0.2 > sky.rad
oconv sky.rad office.rad glaze70.rad mirr_ss.rad > model.oct
rtrace -w -h -opv -I+ $opzioni model.oct < office_sensor.pts > |rcalc
-e '$1=$1;$2=$2;$3=179*(.265074126*$4+.670114631*$5+.064811243*$6)' >
$mo.$da.$hh.V.mss.dat
end
end
end
The problem is : use error - bad month, oconv: sky.rad - empty-file
and, finally, missing name for redirect. Does anybody know how to make
it work?
Thanks in advance,
Valeria

The syntax for gensky is
gensky month day hour:minute [anything else]
In your script you create
gensky -a 45.5 -o 12.33 -m -15 month:day:hour -u -g 0.2
which is not accepted by gensky. Use the line
gensky $mo $da $hh":00" -a 45.50 -o -12.33 -m -15 -u -g 0.2 > sky.rad
instead of your command. I assume that the CSH syntax
otherwise is correct. I have not checked that the output
of $hh":00" returns something like "13:00".
I also noticed that you use a uniform sky here (-u).
This is not realistic sky distribution and only appropriate
in specialist cases. If you want a "standard" sky you should
use "-c" to create an CIE overcast sky (probably not very
accurate for Venice either - I'm sure you get some sun there.).
Regards,
Thomas

Hi,
you must first specify month day hour (without ':' in between!!!), than the options (just type gensky, it will show you the possible ways to call it).
gensky $mo $da $hh -a 45.50 -o -12.33 -m -15 -u -g 0.2 > sky.rad
Should do the job.
However, instead of your foreach loops, you can use the radiance tool 'cnt', which counts thru an array, combined with rcalc and awk, to write a shell script that will do the calculation:
cnt 12 4 18 | rcalc -e '$1=1+$1;$2=(1+$2)*7;$3=$3+4' | awk '{ print "gensky "$1, $2, $3" -a 45.50 -o -12.33 -m -15 -u -g .2 > sky.rad; oconv sky.rad office.rad glaze70.rad mirr_ss.rad > model.oct"; }' > skys.bash
As you see, I did not write the rtace part - as I am too lazy to do all the escaping work for awk. Still, it is just a proposal to do this in an one-liner 
Good luck, CU Lars.
Valeria,
If the following material and source descriptions are *not* in your other .rad, files, then you will only have a description for the sun.
skyfunc glow skyglow
0
4 1 1 1 0
skyglow source sky
0
4 0 0 1 180
skyfunc glow groundglow
0
4 1 1 1 0
groundglow source ground
0
4 0 0 -1 180
If that is the case, put the lines above into a file called, say, sky_glow.rad and include it in the oconv command, e.g:
oconv sky.rad sky_glow.rad office.rad glaze70.rad mirr_ss.rad > model.oct
Also, there's a typo here:
rtrace -w -h -opv -I+ $opzioni model.oct < office_sensor.pts > |rcalc -e '$1=$1;$2=$2;$3=179*(.265074126*$4+.670114631*$5+.064811243*$6)' > $mo.$da.$hh.V.mss.dat
I'm assuming this is all one line, in any case you don't need the ">" redirection before the pipe to rcalc, just delete it.
A presto!

Thank you John,
I forgot the glow description! I've noticed that without the glow
description I have only the sun description and it results 0 lux all
the time.
Thank you,

Thank you Lars! It runs now! I'll try in the other way you suggest me!
