Hello,
I have a couple of questions with regards to the three-phase method
tutorials:
1- Following the Example 1 in the tutorial document titled as "The
Three-Phase Method for Simulating Complex Fenestration with Radiance"
(available at
http://www.radiance-online.org/learning/tutorials/Tutorial-ThreePhaseMethod.pdf)
I have encountered the following error message using the dctimestep (page
21) to generate a rendering:
"fatal - unexpected EOF reading results/south.dmx"
I have checked the content of the south.dmx file generated in the previous
steps and it appears that with the exception of the first 9 lines providing
information such as the Format, Software, Capdate etc, the remaining of the
lines contain NULL values. This is despite the fact that I have not
received any error messages following the Example 1 through each step prior
to this last step where the EOF error is raised.
2- There is another document titled as "Radiance Three Phase Method
Tutorial" (also by Andy McNeil) which I could not find on the Radiance
website but it it published via GitBook at the following link:
https://www.gitbook.com/book/andymcneil/three-phase-method-tutorial/details
Following the Example 1 of this new tutorial document, the 'rcontib' call
is replaced with 'rfluxmtx' to create the view matrix renderings. I have
also attempted to pursue this example step by step, however, the call for
the 'rfluxmtx' for generating view matrix renderings (page 21) raises the
following error message:
"missing hemisphere sampling type"
I have checked the 'rfluxmtx' document describing the application of a
"#@rfluxmtx variable=value" form to pass the sampling basis (eg. h=kf for
full Klems sampling model). However, I could not find the correct syntax to
add this variable to the rfluxmtx command call in the tutorial (page 21) in
response to the "missing hemisphere sampling type" error.
I would appreciate if you could help me with these two questions.
Thank you,
Alireza
Hi Alireza,
There have been a few changes to the programs since this tutorial was written. It would help to know what system you are on (esp. if Windows) and the exact commands you used leading up to the error.
Cheers,

Hi Greg,
Thank you for your response.
I am working on a Windows 7 (64-bit) operating system and I use GitBash
shell for my command line.
Following the description of the two error messages relative to the two
versions of the Three-Phase Method tutorial, I have provided the exact
command line raising the errors
in the Example #1 of both tutorials:
1- Tutorial Document Title: "The Three-Phase Method for Simulating Complex
Fenestration with Radiance"
Access Link:
http://www.radiance-online.org/learning/tutorials/Tutorial-ThreePhaseMethod.pdf
Page # 21
Command: $ dctimestep images/vmx/window_%03d.hdr
data/singleclear.xml results/south.dmx skies/12_21_15.skv >

Error: "fatal - unexpected EOF reading results/south.dmx"
2- Tutorial Document Title: "Radiance Three Phase Method Tutorial"
Access link:
https://www.gitbook.com/book/andymcneil/three-phase-method-tutorial/details
Page # 21
Command: $ vwrays -fa -vf views/back.vf -x 600 -y 600 | rfluxmtx
`vwrays -vf views/back.vf -x 600 -y 600 -d` -n 8 -fac -ab 12 -ad 50000 -lw
2e-5 - objects/window.rad materials/testroom.mat objects/testroom.rad
Error: "C:\Radiance\bin\rfluxmtx.exe: missing hemisphere sampling type!"
I hope the referenced commands would help to give a better description of
how the errors are raised.
Please let me know if you need any further information.
Thank you,
Alireza

Hi Alireza,
Another resource that you can use to learn/test three phase method on
Windows is OpenStudio. OpenStudio prints the commands in the terminal while
running the analysis.
Rob has already addressed many of the issues that you will probably face to
get it to work on Windows. I copied the lines here for a similar
discussion: (http://www.grasshopper3d.com/xn/detail/2985220:Comment:1389864).
You can also find the files attached in the discussion.

Alireza,
I suspect your first error stems from an unexpected or missing header. Can
you open your daylight matrix and sky vector in notepad and respond with
the first 10 lines in each file?
The second tutorial that you've found is meant to replace the old tutorial,
but I've not finished it yet so there may be some inconsistencies. Can you
email the comment line of your window.rad file (the one that starts
#@rfluxmtx) as this is where the sampling basis is specified.

Hi Andy,
Thank you very much for your response.
1) Following your recommendation to provide the first 10 lines in the
daylight matrix and sky vector files:
Daylight matrix file (10 first lines):
#?RADIANCE
oconv materials/box_03.mat objects/box_03.rad sky/sky_white1.rad
rcontrib -c 1000 -e MF:4 -f reinhart.cal -b rbin -bn Nrbins -m sky_mat -faf

NCOMP=3
NCOLS=2306

Sky vector file (10 first lines):

12.399048 12.399048 12.399048
2) I managed to find the error in my process following the Example 1 in the
second tutorial (
https://www.gitbook.com/book/andymcneil/three-phase-method-tutorial/details).
However, I encountered the following error message in the last step using
the dctimestep call to generate renderings:
"fatal - unexpected column count in header"
