Hi Reinier,
You need to use the -y option to specify the number of rows in your
rfluxmtx run so you don't need to do it manually.

Hi all,
I am following the latest approach to the three-phase method as described
in Andy McNeil's 2014 Radiance Workshop Presentation, but when I generate
view matrices my output is botched.
With this command (I realise this is low accuracy, but for the moment I'm
mainly testing workflow) :
rfluxmtx -ab 4 -ad 5000 < ChEast.pts - windows_pts/window_00.rad
material.rad ChEast.rad > viewpts_00.mtx
the header in the viewmatrix is as follows:
#?RADIANCE
oconv -f material.rad ChEast.rad windows_pts/window_01.rad
rcontrib -fo+ -ab 4 -ad 5000 -faa -c 1 -f klems_full.cal -bn
Nkbins -b kbin(0.525501,0.0136168,-0.850684,0,0,1) -m M-nor
SOFTWARE= RADIANCE 4.3a lastmod by nrel_nt
gugliel on rgugliel-W7-VM
CAPDATE= 2015:02:19 12:21:14
GMT= 2015:02:19 12:21:14
NCOMP=3
NCOLS=145
FORMAT=asciiWhen I try to do any matrix multiplication to get the three-phase result,
I get problems with RMTXOP or dctimestep, which complain they can't load
the matrix. If I add the line NROWS=81 (number of sensor points) manually
in the header, I do get results. But I'm trying to run the simulation for a
lot of windows so adding this line each time manually or with a script is a
bit painful. Am I doing something wrong or is this a bug?Additionally, when I try to run dctimestep in annual mode, using the
following command:
dctimestep -n 8760 viewpts_00.mtx grate.xml daylight_00.mtx
annual.smx > test.dat
I get:
'fatal - unexpected EOF reading annual.smx'
even though my annual.smx has 146 rows (for all 146 Tregenza daylight
patches) and 8760 columns.Any idea what is going wrong here?
Many thanks,
