rsensor and annual daylighting simulation

Hello,

There are 30 sensors in the space, each of which has sensor spatial
response file and use rsensor to calculate illuminance values. If I use
three phase method to conduct annual simulation. My current method is to
use: rsensor -h -vf view.vf . to generate the 10000 rays and use these
rays to calcualte V matrix. in other words, I am using three phase method
to calculate 10000 sensor points. At the end, only a single sensor values
are calculated. Is there any better way?

Thanks!

Jia

Hi Jia,

You can use the -c option in rcontrib to average the coefficients of the
10,000 rays.

The command would look something like this:
rsensor -rd 10000 (MoreArguments) . | rcontrib -c 10000 (MoreArguments)
model.oct > sensor.vmx

Thanks Andy! I was thinking to calculate all the readings for 10,000 rays
and then adding them together, which is incorrect and computational
expensive.

Hi Andy,

There is an better way to generate .vmx for all 30 sensors together instead
of manually combining them one by one? Thanks,

Jia
