# DMPlexBuildFromCellList
Build DMPLEX topology from a list of vertices for each cell (common mesh generator output) 
## Synopsis
```
#include "petscdmplex.h"   
#include "petscdmplex.h"   
PetscErrorCode DMPlexBuildFromCellList(DM dm, PetscInt numCells, PetscInt numVertices, PetscInt numCorners, const PetscInt cells[])
```

## Input Parameters

- ***dm -*** The DM
- ***numCells -*** The number of cells owned by this process
- ***numVertices -*** The number of vertices owned by this process, or PETSC_DETERMINE
- ***numCorners -*** The number of vertices for each cell
- ***cells -*** An array of numCells*numCorners numbers, the global vertex numbers for each cell

would have input
```none

cells = [0 1 2  1 3 2]

which would result in the DMPlex

If numVertices is PETSC_DETERMINE, it is computed by PETSc as the maximum vertex index in cells + 1.

Not currently supported in Fortran.
