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 "petscdmplextransform.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
