Radiance example

[Stefano Moret]

Hi,

I'm trying to run the Radiance example on Mac OS, but I get the following error when executing the bash shell script.

ev: Command not found.gensky: Command not found.

I double-checked my environment variables, and they should be alright. 

Here are the lines of the configuration files I've set for BCVTB (Radiance is installed in /radiance folder).

<entry key="BCVTB_RADIANCE_DIR">/radiance/bin</entry>

<entry key="PATH">$BCVTB_HOME/bin:$BCVTB_RADIANCE_DIR:$PATH</entry>

<entry key="RAYPATH">/radiance/lib:.</entry>

Btw, as any of you succeeded in running BCVTB+Radiance on Windows?

Thanks, regards

Stefano

Hi Stefano,

Can you check to make sure ev and gensky are in the folder /radiance/bin?

Are you sure you mean /radiance/bin and not ~/radiance/bin or something else?

Hi Andy,

- yes, ev and gensky are in /radiance/bin

- yes, radiance is in the root folder /radiance.

Hi Stefano,

My apologies for asking basic questions.

Did you close and restart BCVTB after you modified the Radiance path systemVariables-linux.properties? 

What operating system are you using?

please add this line in examples/radiance40/scripts/radiance.csh (after #! /bin/csh ):

echo $PATH > /dev/stderr

Then run the radiance example.

does /radiance/bin appear somewhere in the output in .system.ErrorStream ?

Thanks Andy,

Good catch!

I'm working on Mac OS 10.6.8.

Thanks to your hint I found the problem, basically the Radiance path was naively overwritten by the EnergyPlus one. 

Now I added them together and it works:

<entry key="PATH">

$BCVTB_HOME/bin:$BCVTB_ENERGYPLUS_DIR:$BCVTB_RADIANCE_DIR:$PATH</entry>

Thanks for the hint!

Btw, I've seen the example has never been tested on Windows, is there any development under this point of view? I need to work on Windows for my simulations in E+, it would be nice to integrate Radiance there as well. At the moment I can't couple them in BCVTB due to these OS issues.

Thanks again,

Stefano

Running Radiance with BCVTB on Windows should work just fine.  Though the packaged example won't work.  The included example script is written in c-shell.   You would need to write scripts in DOS batch for windows.

You can download a Radiance installer for Windows from NREL's open studio page:

http://openstudio.nrel.gov/getting-started-developer/getting-started-radiance

good luck.

That's right, I was thinking to install it through cygwin and use bash, but DOS would actually be the native option.

Thanks,

Stefano

Now that NREL is distributing windows installers for RADIANCE, I'd stick with DOS.  The previous users of Radiance with cygwin did so because there wasn't a good option for using Radiance on windows natively. (the desktop radiance binaries were very outdated and the Scons build system was often broken).

There's also the possibility of using E+ on Mac, if you want to stick with bash...

Andy

Ok, thanks. I'm using E+ both on Mac and Windows, but the new release (v7.1) will be only windows, and it has some new functions I need to play around with.
