Hello Everyone,


I am trying to simulate Radiation in chtMultiRegionSimpleFoam.


I have some basic questions related to viewFactor Radiation Model:


1. How can I generate viewFactorsDict file? because when I run FaceAgglomerate it gives the following error:

--> FOAM FATAL IO ERROR: 
cannot open file

file: /home/openfoam/run/radiation_box/constant/viewFactorsDict at line 0.

    From function regIOobject::readStream()
    in file db/regIOobject/regIOobjectRead.C at line 86.

FOAM exiting

And I am getting the same error, when I RUN 'faceAgglomerate'


How can I get this file.



Any help would be highly appreciated.


Thank you
