    Summary

    On the following skewed finite-area mesh, makeWeights function generates inconsistent weights in serial vs. parallel.

    manufactured_finite_area_case_views

    Steps to reproduce

    Use Test-faMesh-edgeInterpolation.zip on the manufactured_finite_area_case.zip in serial vs. parallel, and compare the output of weights.

    Environment information

    • api = 2406
    • HEAD = e4f4c73b
    • compiler = Clang (system) = clang version 15.0.7
    • mpi = SYSTEMOPENMPI = mpirun (Open MPI) 1.10.7.0.5e373bf1fd
    • OS = Description: openSUSE Leap 15.5
    • opts = linux64ClangDPInt32Opt

    Possible fixes

    A potential solution is to ensure that the same algorithm is used for calculating weights for both internal and processor edges.
