[Radiance-general] Using dayfact Script

[R Ganesh]

Hi Greg,

 

I checked in the working directory there was no plots created. The file
name which was given for illumination plot was present in the directory
but its size was 0 bytes no other picture files were present in the
directory. Is there any other way to check dayfact script in my
computer.

I use default shell in ubuntu 8.1 i.e. bash for running the script. I am
currently running binaries radiance V3.9 distributed with ubuntu 8.1.

 

Regards

Ganesh.

Hi Ganesh,

 

The key to your problem is written in the last line of the script output
-- apparently, your version of Unix lacks a "mail" command, so you
didn't get any notification.  I expect your results are sitting in the
file you named in the working directory.  Did you check?  The ximage
command may be used to display it.

 

Cheers,

-Greg

	Dear Radiance Users,
	
	I am beginner in radiance am I am trying to use dayfact script
to create illuminance plot for a simple room. When I run the dayfact
script with the inputs given below  no contour plots were created and no
error message was shown. I request to guide me in getting the plots.
	
	Input for dayfact script is below and the room description is
attached with the mail.
	
	DAYLIGHT FACTOR CALCULATION
	
	This script calculates daylight factors, illuminance levels,
and/or
	energy savings due to daylight on a rectangular workplane and
produces
	a contour plot from the result.  The input is a Radiance scene
description
	(and octree) and the output is one or more color Radiance
pictures.
	
	Have you already calculated an illuminance picture using
dayfact?
	Enter illumpic [none]: 
	Enter octree [none]: room.oct
	Is the z-axis your zenith direction? y
	What is the origin (smallest x y z coordinates) of the
workplane?
	Enter wporig [0 0 0]: 0 0 1
	What is the x and y size (width and length) of the workplane?
	Enter wpsize [1 1]: 3 3
	What calculation options do you want to give to rtrace?
	(It is very important to set the -a* options correctly.)
	Enter rtargs [-ab 1 -ad 256 -as 128 -aa .15 -av .3 .3 .3 -ar
13]: 
	Do you want to save the illuminance picture for later runs?
	Enter illumpic [none]: RoomIlPic.pic
	In what scene file is the gensky command located?
	Enter genskyf [none]: skies/sky_overcast.mat
	# gensky 11 21 12:00 -a 51 -o 0 -m 0 -c
	# gensky 11 21 12:00 -a 51 -o 0 -m 0 -c
	Illuminance contour picture if you want one
	Enter ilpict [none]: RmIlCont.pic
	Daylight factor contour picture if you want one
	Enter dfpict [none]: RmDF.pic
	Energy savings contour picture if you want one
	Enter dspict [none]: RmES.pic
	Workplane design level (lux)
	Enter designlvl [500]: 
	Title for output picture
	Enter title [room 11 21 12]: Rmouptput.pic
	[1] 30406 30411
	Your job is started in the background.
	You will be notified by mail when it is done.
	mail: Command not found.
