Hello,

I have encountered two errors with gendaymtx and dctimestep with the five
phase method tutorial that I would appreciate if you could help me with:

OS X Yosemite 10.10.2
Radiance 5.0.8
Command Line Environment: Terminal

Error #1

Command:

$ gendaymtx -5 -d -m 6 -of skies/OakLand.wea >
matrices/OakLand_direct_m6.smx

Error Message:

gendaymtx: missing solar disk size argument for '-5' option

Error #2

Command:

$ dctimestep -n 8760 -if -o hourlypics/back_%04d.hdr viewpics/back_%03d.hdr
\
bsdf/fullwindow.xml matrices/daylightmatrix.dmx matrices/OakLand.smx

Error Message:

fatal - improper length for binary file 'matrices/Oakland_direct.smx'

description: the 'Oakland_direct.smx' has been generated by the following
command:

$ gendaymtx -of -d skies/OakLand.wea > matrices/OakLand_direct.smx

Thank you for your help,
Alireza

Hi Alireza,

Error #1:
The problem and solution is explained here:

Error #2:
Have you checked that your daylight matrix uses the same sky subdivision as
the sky matrix? The default for gendaymtx is 145 sky divisions.

Hi Andy,

Thank your for your response.

Error#1:

I checked the link and added the 0.53 argument to the -5 option and it
appears to work as I did not received the same error message again.

Error#2:

The 'daylightmatrix.dmx' is generated by the following command using the
MF:1 option as shown in the section 6.5 of the tutorial:

$ genklemsamp -c 1000 -vd 0 -1 0 objects/daymtxsurf.rad | \
rcontrib -c 1000 -ab 2 -ad 1024 -e MF:1 -f reinhart.cal -b rbin -bn Nrbins \
-m sky_glow octs/model_3ph.oct > matrices/daylightmatrix.dmx

Once I run the dctimestep as shown in section 7.6 of the tutorial for the
'three-phase simulation part' of the five-phase process:

$ dctimestep -n 8760 -if -o hourlypics/back_%04d.hdr viewpics/back_%03d.hdr
\
bsdf/fullwindow.xml matrices/daylightmatrix.dmx matrices/OakLand.smx

I receive the error message:

fatal - improper length for binary file 'matrices/Oakland_direct.smx'

The same error is raised when I call dctimestep for the 'direct sun
component of the three-phase part' as well as 'direct sun component using
the model with many suns' as shown in the section 7.6 of
the tutorial:

$ dctimestep -n 8760 -if -o hourlypics_dir/back_%04d.hdr
viewpics_dir/back_%03d.hdr \
bsdf/fullwindow.xml matrices/daylightmatrix_direct.dmx
matrices/OakLand_direct.smx

$ dctimestep -n 8760 -if -o hourlypics_ds/back_%04d.hdr
viewpics_ds/back_%04d.hdr \
matrices/OakLand_direct_m6.smx

Thank you for your help,
Alireza

Hi Alireza,

Try your dctimestep command in Error#2 without the "-n 8760" option. The behavior was changed since the tutorial was written so this option is no longer needed with recent releases of the software. This has been mentioned in earlier threads this month, so you might want to go back and read through those:

Hi Greg and Andy,

Thank you for your responses.
I have excluded the '-n 8760' argument from the 'dctimestep' call and it
does not raise the "improper length" error anymore. However, there is a
couple of other errors raised:

OS X Yosemite 10.10.2
Radiance 5.0.8
Command Line Environment: Terminal

Command:

$ dctimestep -if -o hourlypics/back_%04d.hdr viewpics/back_%03d.hdr \
bsdf/fullwindow.xml matrices/daylightmatrix.dmx matrices/OakLand.smx

Error#1

fatal - cannot find BSDF file 'bsdf/fullwindow.xml'

Description:

In the five-phase method tutorial, there are two BSDF files generated in
".xml" format that are named as "fullwindow_klems.xml" and
"fullwindow_t45.xml". There are no BSDF files named "fullwindow.xml". So I
was wondering which
BSDF xml file is meant to be in the command?

Error#2

dctimestep: cannot open 'hourlypics/back_0001.hdr' for output.

Description:

I passed "fullwindow_klems.xml" instead of "fullwindow.xml" just to see if
the command would run into any other errors and the given dctimestep error
about the hourlypics/ directory is raised. I do not see any directory made
in any previous steps of the tutorial that is named "houlrypics". So I do
not understand what the given error is about.

Best Regards,
Alireza

Alireza,
The klems bsdf is the correct one to use.
you need to create the hourlypics directory:
mkdir hourlypics
