The file should be located at c:\radiance\lib.

If it isn’t your radiance installation probably was not correct.

It can be that you installed at the default locations and HB is having trouble finding it?

If so i recommend to reinstall radiance at C as the home directory.

Hello Abraham,

Thank you for the fast reply. I do have c:\radiance\lib but the file is not there, will try to reinstall Radiance to see if that fixes the problem.

Thank you once more,

Blanca

Abraham,

I reinstalled Radiance but the file is still not there, I’ve checked in other 2 computers and installed it in a brand new one and still nothing. Is there any other way I can get that file?

Thank you,

Blanca

Which version of Radiance are you using. Try this link for installer: https://github.com/NREL/Radiance/releases/tag/5.0

and make sure you’re changing the installation address to “c:\radinace”

Hi @mostapha , I am facing the same problem. Perezlum.cal exist in both DAYSIM and Radiance folders but it still fails and says cannot find the function file. I tried Radiance 5.1 (the one in the instruction), 5.2, the link that you mentioned for 5.0 but none works. Could you please help me?
Thanks in advance!
