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 dimdimensional
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 hardcoded numbers of vertices, neighbors and so on, since it can be used dimension independently.

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.

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 1198 of file geometry_info.h.

static 
Number of faces a cell has.
Definition at line 1203 of file geometry_info.h.

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.

static 
Number of vertices a cell has.
Definition at line 1225 of file geometry_info.h.

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
.

Number of lines each face has.

Number of quads on each face.

Number of lines of a cell.

Number of quadrilaterals of a cell.

static 
Number of hexahedra of a cell.

static 
Rearrange vertices for UCD output. For a cell being written in UCD format, each entry in this field contains the number of a vertex in deal.II
that corresponds to the UCD numbering at this location.
Typical example: write a cell and arrange the vertices, such that UCD understands them.
As the vertex numbering in deal.II versions <= 5.1 happened to coincide with the UCD numbering, this field can also be used like a old_to_lexicographic mapping.

static 
Rearrange vertices for OpenDX output. For a cell being written in OpenDX format, each entry in this field contains the number of a vertex in deal.II
that corresponds to the DX numbering at this location.
Typical example: write a cell and arrange the vertices, such that OpenDX understands them.
