dm | - The DM | |
numCells | - The number of cells owned by this process | |
numVertices | - The number of vertices owned by this process, or PETSC_DETERMINE | |
numCorners | - The number of vertices for each cell | |
cells | - An array of numCells*numCorners numbers, the global vertex numbers for each cell |

1would have input
numCells = 2, numVertices = 4
cells = [0 1 2 1 3 2]
which would result in the DMPlex

If numVertices is PETSC_DETERMINE, it is computed by PETSc as the maximum vertex index in cells + 1.
