DMPlexCreateDoublet - Creates a mesh of two cells of the specified type, optionally with later refinement.

Collective

Input Parameters:

+ comm - The communicator for the DM object

. dim - The spatial dimension

. simplex - Flag for simplicial cells, otherwise they are tensor product cells

. interpolate - Flag to create intermediate mesh pieces (edges, faces)

. refinementUniform - Flag for uniform parallel refinement

- refinementLimit - A nonzero number indicates the largest admissible volume for a refined cell

Output Parameter:

. dm - The DM object

Level: beginner

DMPLEX = "plex" - A DM object that encapsulates an unstructured mesh, or CW Complex, which can be expressed using a Hasse Diagram.

2489

In the local representation, Vecs contain all unknowns in the interior and shared boundary. This is

2490

specified by a PetscSection object. Ownership in the global representation is determined by

2491

ownership of the underlying DMPlex points. This is specified by another PetscSection object.

2492

2493

Options Database Keys:

2494

+ -dm_plex_hash_location - Use grid hashing for point location

2495

. -dm_plex_partition_balance - Attempt to evenly divide points on partition boundary between processes

2496

. -dm_plex_remesh_bd - Allow changes to the boundary on remeshing

2497

. -dm_plex_max_projection_height - Maxmimum mesh point height used to project locally

2498

. -dm_plex_regular_refinement - Use special nested projection algorithm for regular refinement

2499

. -dm_plex_check_symmetry - Check that the adjacency information in the mesh is symmetric

2500

. -dm_plex_check_skeleton <celltype> - Check that each cell has the correct number of vertices

2501

. -dm_plex_check_faces <celltype> - Check that the faces of each cell give a vertex order this is consistent with what we expect from the cell type

2502

. -dm_plex_check_geometry - Check that cells have positive volume

2503

. -dm_view :mesh.tex:ascii_latex - View the mesh in LaTeX/TikZ

2504

. -dm_plex_view_scale <num> - Scale the TikZ

2505

- -dm_plex_print_fem <num> - View FEM assembly information, such as element vectors and matrices
