Summary0000745: Radiation does not pass through AMI interface (view factor model)
DescriptionRadiation does not pass through AMI interface. View factor model is used.

See notes.png picture in the attached zip-file to understand problem better. Example domain, AMI location, result of simulation and correct result are shown in notes.png
Example case is also inside zip archive.

I think 'faceAgglomerate' and 'viewFactorsGen' work incorrectly with AMI. But it probably easy to manage since they need just ignore AMI boundaries, since there is no radiation processes on them.
Steps To ReproduceUnpack zip. Run file 'Allrun' in 'example' subfolder.
Additional InformationThe correct solution can be obtained with some tricks:
1) remove AMI boundaries from 'constant/polyMesh/boundary' file
2) run 'faceAgglomerate' then 'viewFactorsGen'
3) copy produced files 'constant/F' to 'constant/F_noAMI' and 'constant/globalFaceFaces' to 'constant/globalFaceFaces_noAMI'
4) put AMI boundaries back to 'constant/polyMesh/boundary' file
5) run 'faceAgglomerate' and 'viewFactorsGen'
6) replace 'constant/globalFaceFaces' by 'constant/globalFaceFaces_noAMI' and 'constant/F' by 'constant/F_noAMI'
7) run solver

Allrun file which follow the above routine can be found in 'corrected' subfolder of the attached zip archive.

To solve the problem a small change should be introduced to searchingEngine.H. Just to skip cyclicAMI patches in a cycle.

forAll(Qrb, patchI)
{
    const polyPatch& pp = patches[patchI];
   if (!isA<processorPolyPatch>(pp) && !isA<cyclicAMIPolyPatch>(pp))
    {
          includePatches.insert(patchI);
    }
}

Please account for this in the main branch.

Thanks for report and solution!
