Detailed Description
template<int dim, class GridImp>
class Dune::ALU3dGridEntity< 0, dim, GridImp >
A Grid is a container of grid entities. An entity is parametrized by the codimension. An entity of codimension c in dimension d is a d-c dimensional object.
Entities of codimension 0 ("elements") are defined through template specialization. Note that this specialization has an extended interface compared to the general case
Entities of codimension 0 allow to visit all neighbors, where a neighbor is an entity of codimension 0 which has a common entity of codimension 1 with the These neighbors are accessed via an iterator. This allows the implementation of non-matching meshes. The number of neigbors may be different from the number of faces/edges of an element!
Member Function Documentation
◆ count()
|
inline |
Intra-element access to entities of codimension cc > codim. Return number of entities with codimension cc.
◆ father()
| EntityPointer Dune::ALU3dGridEntity< 0, dim, GridImp >::father | ( | ) | const |
Inter-level access to father element on coarser grid. Assumes that meshes are nested.
◆ geometryInFather()
| LocalGeometry Dune::ALU3dGridEntity< 0, dim, GridImp >::geometryInFather | ( | ) | const |
Location of this element relative to the reference element of the father. This is sufficient to interpolate all dofs in conforming case. Nonconforming may require access to neighbors of father and computations with local coordinates. On the fly case is somewhat inefficient since dofs are visited several times. If we store interpolation matrices, this is tolerable. We assume that on-the-fly implementation of numerical algorithms is only done for simple discretizations. Assumes that meshes are nested.
◆ getSubIndex()
| int Dune::ALU3dGridEntity< 0, dim, GridImp >::getSubIndex | ( | int | i | ) | const |
return index of sub entity with codim = cc and local number i i.e. return global number of vertex i for use in hierarchical index set
◆ hbegin()
|
inline |
Inter-level access to son elements on higher levels<=maxlevel. This is provided for sparsely stored nested unstructured meshes. Returns iterator to first son.
◆ ileafbegin()
|
inline |
Access to intersection with neighboring elements that are leaf elements. A neighbor is an entity of codimension 0 which has an entity of codimension 1 in commen with this entity. Access to neighbors is provided using iterators. This allows meshes to be nonmatching. Returns iterator referencing the first neighbor.
References Dune::ALU3dGridEntity< cd, dim, GridImp >::level().
◆ ilevelbegin()
|
inline |
Intra-level access to intersection with neighboring elements. A neighbor is an entity of codimension 0 which has an entity of codimension 1 in commen with this entity. Access to neighbors is provided using iterators. This allows meshes to be nonmatching. Returns iterator referencing the first neighbor.
References Dune::ALU3dGridEntity< cd, dim, GridImp >::grid(), and Dune::ALU3dGridEntity< cd, dim, GridImp >::level().
◆ mark()
| bool Dune::ALU3dGridEntity< 0, dim, GridImp >::mark | ( | int | refCount | ) | const |
marks an element for refCount refines. if refCount is negative the element is coarsend -refCount times mark returns true if element was marked, otherwise false
◆ setElement()
|
inline |
private methods, but public because of datahandle and template arguments of these methods
◆ subEntities()
|
inline |
Intra-element access to entities of codimension cc > codim. Return number of entities with codimension cc.
References Dune::ALU3dGridEntity< cd, dim, GridImp >::grid().
◆ subEntity()
| Codim< codim >::EntityPointer Dune::ALU3dGridEntity< 0, dim, GridImp >::subEntity | ( | int | i | ) | const |
Provide access to mesh entity i of given codimension. Entities are numbered 0 ... count<cc>()-1
◆ subIndex()
| int Dune::ALU3dGridEntity< 0, dim, GridImp >::subIndex | ( | int | i, |
| unsigned int | codim | ||
| ) | const |
return index of sub entity with codim = cc and local number i i.e. return global number of vertex i for use in hierarchical index set
