Is it possible to write dummy vertices in the blockMesh file which are not used to create a block afterwards and not getting an error?

Hi Alexander,
yes, you can add dummy vertices in the blockMeshDict without using them; there should be no error message. Martin |

The user manual on pg U-126, mentions, "The point list cannot contain two different points
at an exactly identical position nor any point that is not part at least one face" |

This point list mentioned in the user guide refers to the points in the final mesh, id est the constant/polyMesh/points, whereas the blockMeshDict file can have dummy points. The dummy points in the blockMeshDict are very useful for debugging purpose and for automatic mesh generation algorithms.
