Create distributed DMPLEX from a list of vertices for each cell (common mesh generator output)


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


Input Parameters#

  • comm - The communicator

  • dim - The topological dimension of the mesh

  • numCells - The number of cells owned by this process

  • numVertices - The number of vertices owned by this process, or PETSC_DECIDE

  • NVertices - The global number of vertices, or PETSC_DECIDE

  • numCorners - The number of vertices for each cell

  • interpolate - Flag indicating that intermediate mesh entities (faces, edges) should be created automatically

  • cells - An array of numCells*numCorners numbers, the global vertex numbers for each cell

  • spaceDim - The spatial dimension used for coordinates

  • vertexCoords - An array of numVertices*spaceDim numbers, the coordinates of each vertex

Output Parameters#

  • dm - The DM

  • vertexSF - (Optional) PetscSF describing complete vertex ownership

  • verticesAdj - (Optional) vertex adjacency array


This function is just a convenient sequence of DMCreate(), DMSetType(), DMSetDimension(), DMPlexBuildFromCellListParallel(), DMPlexInterpolate(), DMPlexBuildCoordinatesFromCellListParallel()

See DMPlexBuildFromCellListParallel() for an example and details about the topology-related parameters.

See DMPlexBuildCoordinatesFromCellListParallel() for details about the geometry-related parameters.
