Hi all,

I'm receiving the following error when running a coal combustion (with radiation) solver:

--> FOAM FATAL ERROR: (openfoam-2012)
Patch : base is not found in the boundaryRadiationProperties. Please add it

    From Foam::tmp<Foam::Field<double>> Foam::radiation::boundaryRadiationProperties::emissivity(int, int, Foam::Field<Foam::Vector<double>> *, Foam::Field<double> *) const
    in file submodels/boundaryRadiationProperties/boundaryRadiationProperties.C at line 128

In particular, the error occurs when the solver calls radiation->correct(). It seems to think that I haven't defined BCs for patch, even though I definitely have. I checked my boundaryRadiationProperties dict, which does contain a wildcard for all patches. To make extra sure it wasn't the dictionary, I even added an explicit dictionary entry for patch base, to no success:

For reference, I'm using the P1 radiation model with constantAbsorptionEmission, though this error still appears with different choices of radiation model:

Any ideas where this issue could be originating from?

I am having the same issue with buoyantPimpleFoam with P1 radiation model.

Did you find the reason for this?

Edit:

I am using OpenFOAM-v2212, I'm not sure if they changed things from older versions and/or the foundation versions but looking at the source code I figured out how the radiationBoundaryProperties should look.

Notes:
- It should be in the constant folder
- in the file header it should be labeled "class dictionary;"
- You can also set reflectivity and transmissivity, but not including those does not seem to throw any errors.
- you can set band-based emissivity, absorptivity, etc. values here, not sure specifically how though but the source code eludes to it.
- symmetry patches are not type symmetry here, they are type of a type like any other wall/patch BC (i use type lookup for my symmetry surfaces).

My error was actually caused by the dictionary name- as I was using custom code to read the boundary radiation dict file I had to change the name to match what was expected.

I doubt this is the case for you- what is the error that you are getting exactly?

[pm11dt]

It was the the same error you got where it said it could not find the radiation boundary properties for patch "..." and told me to please add it.

When looking at the C code it throws this error pretty much as a 'catch-all' response to any input error to the boundaryRadiationProperties file - which i think could be improved for usability.

[pbevington]

Looking at your provided file it looks like absorptivity is misspelled for patch other_patches. Maybe thats the issue?

[pm11dt]

That is interesting because my case is running now with no issues, good spot though! Saved me a weekends worth of rerunning simulations.
