DMPlexBuildFromCellList#
Build DMPLEX
topology from a list of vertices for each cell (common mesh generator output)
Synopsis#
#include "petscdmplex.h"
#include "petscdmplex.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 numCells*numCorners numbers, 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.
