DMPlexBuildFromCellList#
Build DMPLEX topology from a list of vertices for each cell (common mesh generator output)
Synopsis#
#include "petscdmplex.h"   
#include "petscdmplextransform.h"   
PetscErrorCode DMPlexBuildFromCellList(DM dm, PetscInt numCells, PetscInt numVertices, PetscInt numCorners, const PetscInt cells[])
Collective; No Fortran Support
Input Parameters#
- 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 - numCellsx- numCornersnumbers, the global vertex numbers for each cell

would 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.
