# DMPlexCreateHexCylinderMesh
Creates a mesh on the tensor product of the unit interval with the circle (cylinder) using hexahedra. 
## Synopsis
```
#include "petscdmplex.h"   
#include "petscdmplex.h"   
PetscErrorCode DMPlexCreateHexCylinderMesh(MPI_Comm comm, DMBoundaryType periodicZ, DM *dm)
```

## Input Parameters

- ***comm      -*** The communicator for the `DM` object
- ***periodicZ -*** The boundary type for the Z direction



## Output Parameter

- ***dm  -*** The DM object





## Note

## Here is the output numbering looking from the bottom of the cylinder
