Hello all -

I’m trying to work through some 3phase (likely going to 5phase) methods with the new tutorials (haven’t done it since Andy’s original tutorial).

Everything seems to be working out as expected when I work through with normal Klems patches. I had some oddities in my data (200k lux vertical illum for some summer hours) so thought I’d try to run at MF4 to see if the larger sky patches were the culprit.

I was able to run all the individual matrices, but the combination at the dctimestep command gives me an error of “fatal - unexpected row count in header”.

Using getinfo on my MF4 matrices, I get:

**vmtx**

rcontrib -fo+ -ab 12 -ad 50000 -lw 2e-6 -w -n 96 -I+ -faa -c 1 -f reinhartb.cal -p MF=4,rNx=0.8232,rNy=0.567752,rNz=0,Ux=0,Uy=0,Uz=1,RHS=+1 -bn Nrbins -b rbin -m A_GLAZ

NCOMP=3

NCOLS=2305

**dmtx**

rcontrib -fo+ -ab 2 -ad 1000 -lw 1e-4 -w -n 96 -fdf -c 1000 -f reinhartb.cal -p MF=4,rNx=0,rNy=0,rNz=-1,Ux=0,Uy=1,Uz=0,RHS=+1 -bn Nrbins -b rbin -m skyglow -bn 1 -b if(-Dx

0-Dy0-Dz*1,0,-1) -m groundglow -y 2305

NCOMP=3

NROWS=2305

NCOLS=2306

BigEndian=0

FORMAT=float

**skymtx**

gendaymtx -m 4 wea/LAX.wea

LATLONG= 33.93000000 -118.40000000

NROWS=2306

NCOLS=8760

NCOMP=3

**bsdf** - have tried a few different ones but all get same error

My geometry for vmtx & dmtx (same geometry) has the following line to direct rfluxmtx -

#@rfluxmtx h=r4 u=Z

Not really sure what’s happening, any help is much appreciated (I’m sure it’s something simple / user input error). I’m going to try to see if 5phase on the ‘working’ klems simulation solves my issues in the meantime.

Just for clarity / my own peace of mind, the view matrix -p MF… bit is for the geometry, but that line in the daylight matrix represents the orientation of the sky right? The window geometry is the same, so just want to make sure that the correct orientation is known. I’m guessing yes, but all the rfluxmtx ‘shortcuts’ compared to Andy’s original makes me curious to know it all falls in line. Again I’m sure it does, just want to make sure. Some simple tests of a box with a skylight all seems to translate correctly, but checking for my own sanity as I try to troubleshoot all this stuff.

Thanks in advance, hope all is well with everyone out there!
