DMPolytopeType

This describes the polytope represented by each cell.

Synopsis

typedef enum {DM_POLYTOPE_POINT, DM_POLYTOPE_SEGMENT, DM_POLYTOPE_POINT_PRISM_TENSOR, DM_POLYTOPE_TRIANGLE, DM_POLYTOPE_QUADRILATERAL, DM_POLYTOPE_SEG_PRISM_TENSOR, DM_POLYTOPE_TETRAHEDRON, DM_POLYTOPE_HEXAHEDRON, DM_POLYTOPE_TRI_PRISM, DM_POLYTOPE_TRI_PRISM_TENSOR, DM_POLYTOPE_QUAD_PRISM_TENSOR, DM_POLYTOPE_PYRAMID, DM_POLYTOPE_FV_GHOST, DM_POLYTOPE_INTERIOR_GHOST, DM_POLYTOPE_UNKNOWN, DM_NUM_POLYTOPES} DMPolytopeType;

While most operations only need the topology information in the Plex, we must sometimes have the user specify a polytope. For instance, when interpolating from a cell-vertex mesh, the type of polytope can be ambiguous. Also, Plex allows different symmetries of prism cell with the same constituent points. Normally these types are autoamtically inferred and the user does not specify them.
