Hello,

I´m working to get the ZoneProperty:UserViewFactors:bySurfaceName to work on a test file.

So far, with the great help from Radiance developers we have found a way to automate the writing of these viewfactors. However, once written, the test file keeps throwing the same error as before

Severe Problem in interior solar distribution calculation (CHKBKS)

Is there any specific field in the idf where I need to enable the use of these ZoneProperty:UserViewFactors:bySurfaceName?

The files are here: original model and viewfactor model.

Thanks, Rafael
