DMPlexCreateFromCellListParallelPetsc#
Create distributed DMPLEX from a list of vertices for each cell (common mesh generator output) where all cells have the same celltype
Synopsis#
#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)
Collective
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#
Notes#
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.
