Summary0003203: blockMesh false faces on axis in wedge block
When generating a mesh for 2D axisymmetric case with blockMesh, an invalid mesh results for some block parameter combinations. The mesh error seems to emanate from that the axis (aligned with the collapsed block edges) has a non-zero amount of faces (although fewer than the number of edges along the axis).

Same case works fine with OpenFOAM-5.x.
Steps To Reproduce1) Unpack attached example case
2a) blockMesh -dict system/blockMeshDict_OK # Should produce a valid mesh ( axis face count = 0)
2b) blockMesh -dict system/blockMeshDict_ERR # Should produce an invalid mesh (axis face count = 2)
3) checkMesh #Floating pt exception
Additional InformationThe problem is also present when running with docker image
TagsNo tags attached.
