[esp-r] Re: radiance

Dear Jon, 

I tried and it seems to go a bit further, but I still get the error messages file doesn't exist : .../rad/type2_phd_b6_treese_day_fa.opt when calculate daylight factors that in fact are all equal to zero. Do you know what the problem may be? 

Let me know, 
Thank you
Arianna

For radiance export and calculations to work correctly you should start the project manager
from the model cfg folder.  We checked this out a few days ago with a new linux machine
setup and the pattern should be the same for cygwin.

Ciao Gian Luca, grazie per la risposta!

I had found the same path that you mentioned through "export current model" and then "radiance" however there is a problem. When I open the radiance desktop I create a file .rcf and then create a scene interactively or silently (I tried both options). I choose daylight factors and select a zone.
I choose as a surface the base, I create a grid inside, I choose a scene name (I gave it the name 1 for simplicity), a root name (I gave it the same name 1) and I get the message: Problem detected while opening 1.sky and problem detected while opening 1.rif., then I proceed with the simulation, I get the two same error messages and the radiance desktop shuts.

Does anyone know what the problem may be? Please great people, let me know.

Regards,
Arianna

Hi Arianna,
I am far from being an ESP-r expert or a Radiance expert, but I'll
give you the information I have hoping it might be useful.

The menu steps to get daylight factors with Radiance from ESP-r is
short: browse/simulate -> simulation -> visual impact -> daylight
factors.

I think that you should install Radiance in Cygwin from the source.

I remember that the first ESP-r precompiled version for Cygwin came
with Radiance included, so it is likely that the compilation of
Radiance for Cygwin is still possible. Said that, I can't assure it
will work, because my experience with Cygwin is that compilations from
sources often fail.

I remember that when I installed Radiance for Linux it was crucial
that the Radpath Environment variable was specified in the bash
configuration file (/etc/.bashr), as recommended I think in the
Radiance's Readme file.

Best regards

Gian Luca Brunetti
