#include "petscdmplex.h" PetscErrorCode DMPlexCreateFromCellList(MPI_Comm comm, PetscInt dim, PetscInt numCells, PetscInt numVertices, PetscInt numCorners, PetscBool interpolate, const int cells[], PetscInt spaceDim, const double vertexCoords[], DM *dm)
| comm | - The communicator | |
| dim | - The topological dimension of the mesh | |
| numCells | - The number of cells | |
| numVertices | - The number of vertices | |
| 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 vertices for each cell | |
| spaceDim | - The spatial dimension used for coordinates | |
| vertexCoords | - An array of numVertices*spaceDim numbers, the coordinates of each vertex |
Note: Two triangles sharing a face

would have input
numCells = 2, numVertices = 4
cells = [0 1 2 1 3 2]
which would result in the DMPlex
