| Hello In the attached test, I read a small grid made in gmsh with periodic bc. This is a 2d mesh. The cell numbers are shown in the figure. All faces have length = 2.5 But using PetscFVFaceGeom I am getting length of 7.5 for some faces. E.g., face: 59, centroid = 3.750000, 2.500000, normal = 0.000000, -7.500000 ===> Face length incorrect = 7.500000, should be 2.5 support[0] = 11, cent = 8.750000, 3.750000, area = 6.250000 support[1] = 15, cent = 8.750000, 1.250000, area = 6.250000 There are also errors in the orientation of normal. If we disable periodicity in geo file, this error goes away. Thanks praveen |
