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,
