Hello all!!

I have tried to use wideBandAbsorptionEmission model.

But I don't know the form of BC.

This is the constant directory.
Code:

            }
        }
    }
What form of code can I modify to use the wideBandAbsorptionEmissionModel?

Thank you for replying in advance.

Best regards.

Hello.

I have tried to use 'wideBandAbsorptionEmission' model.
But it is hard to use.

What is the problem ??
I think some codes in radiationProperties file was wrong.

Actually I don't know the lookuptable's function.
So I set lookuptablefilename as "thermo.compressiblegas"

And this is thermo.compressiblegas

Actually I don't know the lookuptable's function.
So I set lookuptablefilename as "thermo.compressiblegas"

And this is thermo.compressiblegas

Any reply is okay.

Best regards.
I know I am a few years too late but just for anyone who is still struggling with lookUpTable, you have to write none in lookUp table:
lookUpTableFileName none;
then paste the band0 code written in radiation properties file inside constant folder as stated in Openfoam guide.

Bushra.
