Topological description of zero dimensional cells, i.e. points. This class might not look too useful but often is if in a certain dimension we would like to enquire information about objects with dimension one lower than the present, e.g. about faces.
This class contains as static members information on vertices and faces of a dim-dimensional grid cell. The interface is the same for all dimensions. If a value is of no use in a low dimensional cell, it is (correctly) set to zero, e.g. max_children_per_face in 1d.
This information should always replace hard-coded numbers of vertices, neighbors and so on, since it can be used dimension independently.

| static unsigned int GeometryInfo< 0 >::n_children | ( | const RefinementCase< 0 > & | refinement_case ) | [static] |
Return the number of children of a cell (or face) refined with ref_case. Since we are concerned here with points, the number of children is equal to one.
const unsigned int GeometryInfo< 0 >::max_children_per_cell = 1 [static] |
Maximum number of children of a cell, i.e. the number of children of an isotropically refined cell.
If a cell is refined anisotropically, the actual number of children may be less than the value given here.
Definition at line 805 of file geometry_info.h.
const unsigned int GeometryInfo< 0 >::faces_per_cell = 0 [static] |
Number of faces a cell has.
Definition at line 810 of file geometry_info.h.
const unsigned int GeometryInfo< 0 >::max_children_per_face = 0 [static] |
Maximum number of children of a refined face, i.e. the number of children of an isotropically refined face.
If a cell is refined anisotropically, the actual number of children may be less than the value given here.
Definition at line 823 of file geometry_info.h.
const unsigned int GeometryInfo< 0 >::vertices_per_cell = 1 [static] |
Number of vertices a cell has.
Definition at line 838 of file geometry_info.h.
const unsigned int GeometryInfo< 0 >::vertices_per_face = 0 [static] |
Number of vertices each face has. Since this is not useful in one dimension, we provide a useless number (in the hope that a compiler may warn when it sees constructs like for (i=0; i<vertices_per_face; ++i), at least if i is an unsigned int.
Definition at line 849 of file geometry_info.h.
const unsigned int GeometryInfo< 0 >::lines_per_face = 0 [static] |
Number of lines each face has.
Definition at line 854 of file geometry_info.h.
const unsigned int GeometryInfo< 0 >::quads_per_face = 0 [static] |
Number of quads on each face.
Definition at line 859 of file geometry_info.h.
const unsigned int GeometryInfo< 0 >::lines_per_cell = 0 [static] |
Number of lines of a cell.
Definition at line 864 of file geometry_info.h.
const unsigned int GeometryInfo< 0 >::quads_per_cell = 0 [static] |
Number of quadrilaterals of a cell.
Definition at line 870 of file geometry_info.h.
const unsigned int GeometryInfo< 0 >::hexes_per_cell = 0 [static] |
Number of hexahedra of a cell.
