Hi Mostapha,
Thank you - helpful! Where is this behaviour documented? I could not find it in the rfluxmtx or rcontrib manpages.
Best,

Subject: [Radiance-general] Three-phase method troubles: NROWS missing
after rfluxmtx

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=ascii
When 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,
Reinier

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.
Cheers,
Mostapha
