It contains:

  • a script "rht_several_enclosures.cpp" solving radiative heat transfer problems for several gray cavities
  • three cases (rectangular cavity, triangular cavity, and cylindrical cavity) in 2d and 3d with comparisons with literature
  • computation of view factors in unobstructed cavities (2d and 3d) with tests using numerical integration

it closes the following issues

The current status of the branch will not resolve issue 1892. However, in order to include changes to solve the other three issues, I think that a first merge could be beneficial.

@prudhomm CI seems to fail because the cases folder is not found for the view factor test cases (which pass on my side). I don't understand how to solve the problem on Buildkite, as it seems to point to the right path, and the files exist in testsuite/feelviewfactor/casas

@vincentchabannes I could not understand how to solve the problem concerning the test on view factors on Buildkite
