It is equally applicable to scalar, vector, and tensor solution variables. The total contribution of the symmetry plane cell faces to the next-to-symmetry-plane cells is decomposed into implicit and explicit parts, allowing the use of segregated solution algorithms. Using several unstructured mesh test cases, the derived symmetry plane discretizations are shown to be consistent with the discretization on the internal faces.enContinuum mechanicsFinite-volume methodSymmetry planeJournal Article831-2122310.1080/10407790.2022.21050732022-08-11IRCLA/2017/4518/EPSRC-CDT/358416/RC/3872https://creativecommons.org/licenses/by/3.0/ie/
