:orphan: # 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 ## See Also [](ch_unstructured), `DM`, `DMPLEX`, `DMPlexCreateFromCellListParallelPetsc()`, `DMPlexBuildFromCellList()`, `DMPlexBuildCoordinatesFromCellList()`, `DMPlexCreateFromDAG()`, `DMPlexCreate()` ## Level intermediate ## Location src/dm/impls/plex/plexcreate.c ## Examples src/dm/tutorials/ex20.c
