# DMPlexCreateHypercubicMesh

Creates a periodic mesh on the tensor product of unit intervals using only vertices and edges.

## Synopsis

    #include "petscdmplex.h"
    #include "petscdmplex.h"
    PetscErrorCode DMPlexCreateHypercubicMesh(MPI_Comm comm, PetscInt dim, const PetscInt edges[], const PetscReal lower[], const PetscReal upper[], DM *dm)

Collective

## Input Parameters

- comm - The communicator for the DM object

- dim - The spatial dimension

- edges - Number of edges per dimension, or `NULL` for (1,) in 1D and (2, 2) in 2D and (1, 1, 1) in 3D

- lower - The lower left corner, or `NULL` for (0, 0, 0)

- upper - The upper right corner, or `NULL` for (1, 1, 1)

## Output Parameter

- dm - The DM object

## Note

If you want to customize this mesh using options, you just need to

      DMCreate(comm, &dm);
      DMSetType(dm, DMPLEX);
      DMSetFromOptions(dm);

and use the options on the `DMSetFromOptions()` page.

The vertices are numbered is lexicographic order, and the dim edges exiting a vertex in the positive orthant are number consecutively,
