PetscErrorCode DMPlexCreateHexCylinderMesh(MPI_Comm comm, DMBoundaryType periodicZ, DM *dm)

Collective

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:
