DMPlexCreateFromCellListPetsc#

Create DMPLEX from a list of vertices for each cell (common mesh generator output), but only process 0 takes in the input

Synopsis#

#include "petscdmplex.h"   
#include "petscdmplex.h"   
PetscErrorCode DMPlexCreateFromCellListPetsc(MPI_Comm comm, PetscInt dim, PetscInt numCells, PetscInt numVertices, PetscInt numCorners, PetscBool interpolate, const PetscInt cells[], PetscInt spaceDim, const PetscReal vertexCoords[], DM *dm)

Collective

Input Parameters#

comm - The communicator
dim - The topological dimension of the mesh
numCells - The number of cells, only on process 0
numVertices - The number of vertices owned by this process, or PETSC_DECIDE, only on process 0
numCorners - The number of vertices for each cell, only on process 0
interpolate - Flag indicating that intermediate mesh entities (faces, edges) should be created automatically
cells - An array of numCells*numCorners numbers, the vertices for each cell, only on process 0
spaceDim - The spatial dimension used for coordinates
vertexCoords - An array of numVertices*spaceDim numbers, the coordinates of each vertex, only on process 0

Output Parameter#

dm - The DM, which only has points on process 0

Notes#

This function is just a convenient sequence of DMCreate(), DMSetType(), DMSetDimension(), DMPlexBuildFromCellList(), DMPlexInterpolate(), DMPlexBuildCoordinatesFromCellList()

See DMPlexBuildFromCellList() for an example and details about the topology-related parameters. See DMPlexBuildCoordinatesFromCellList() for details about the geometry-related parameters. See DMPlexCreateFromCellListParallelPetsc() for parallel input
