gendyamtx - cumulative results

Hello All,

If I want to show cumulative results (images), eg lux hrs per year or lux hrs per month, what is the right way to do this for the 3 phase with dctimestep. So for example with an annual sky matrix generated with gendaymtx, do I sum this up somehow and then apply?

Thanks,

-Jack

I think the simple answer is that gendaymtx currently doesn't support 3 phase. Weah.

Guess I'd better read that thing. Initially, it did not support 3 phase. Hopefully Andy or Greg or someone else who actually knows what the hell's going on can answer your question. =8-)

Hi Jack,

I think the easiest method would be to extract the hours you want to accumulate from your WEA file, send them through gendaymtx and dctimestep like so:

  gendaymtx -of subyear.wea > subyear1.smx
  dctimestep -if -n 720 -o win1w_%03d.hdr winterior1w.vmx blinds30.xml westelev.dmx subyear1.smx
  pcomb win1w_*.hdr > win1w_sum.hdr
  rm win1w_*.hdr

This will generate 720 images corresponding to a month's worth of hourly inputs from window #1 on the west elevation. The above steps (except the first) will have to be repeated for your different windows. If you do a year at a time, you'll have to sum all these images together in batches, since pcomb only handles up to 1024 images at a time (so long as you don't run into system limits first).

I hope this addresses your question. To be honest, I've never done anything like this and I'm not entirely sure I got it right.

Cheers,
-Greg

Actually, I just realized that you could shortcut this quite a bit by summing together your time steps out of gendaymtx. You should be able to run:

gendaymtx -od jan.wea | total -id3 -720 > jan.sky
dctimestep winterior1w.vmx blinds30.xml westelev.dmx jan.sky > win1w_jan.hdr

Again, you'll need to run dctimestep for each of your windows and sum the results, but it should be a whole lot quicker this way. If you want to sum up a whole year, just change the -720 option on total to -8160 (or whatever).

Cheers,
-Greg

Hi Greg,

Excellent! This is what I was wondering about as a solution.

I will give this a try.

Thanks,

Oh, yeah, and the number used in total needs to match the number of days in the month, so I kind of blew it assuming January has 30 days in my example! (Should have been "total -id3 -744".) This works because gendaymtx outputs time steps as columns in the matrix (inside sort). The final output will contain 3 ASCII triplets for each patch, so you don't need to change anything for different -m options to gendaymtx. You just need to make sure your matrix dimensions are expecting the right number of patches.

Best,
-Greg
