Hi Mostapha,

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

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.

Hi Reinier,

I don't think it is documented yet (or is it?). I had the same issue while
ago and Greg helped me to get it solved so that's why I knew.

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 Reiner,

It's true that this behavior is not properly documented. If you can suggest a logical place where you would expect to find it, perhaps I can add the appropriate text.

Since rfluxmtx and rmtxop are new, the documentation is not as complete as it should be.

Cheers,

Thanks, Mostapha! We get the number of points from the input file (created by the OpenStudio-to-Radiance model translator), here:
https://github.com/NREL/OpenStudio/blob/develop/openstudiocore/ruby/openstudio/radiance/DaylightSim-Simple.rb#L375-377

...then pass that to the -y option to rfluxmtx here:
https://github.com/NREL/OpenStudio/blob/develop/openstudiocore/ruby/openstudio/radiance/DaylightSim-Simple.rb#L433

BTW this was all merged to the main develop branch just last week; we are testing it and documenting it now and this whole 3-phase/shade control thing will be included in OpenStudio v1.7.0 next month, and it'll be in the next iteration release for bleeding edge types, next week. =)

Hi Greg, et. al,

Is there any chance that you can also add some notes about the headings.
There are couple of them in Andy's presentation for .rad or sky files (e.g
#@rfluxmtx h=kf u=+Y or #@rfluxmtx h=u u=Y). I wonder what are other
options available.
