[Radiance-general] Errors with 'gendaymtx' and 'dctimestep'

[Alireza Hashemloo]

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
