Detailed Description
class Dune::IdentityGridLeafIntersection< GridImp >
An intersection with a leaf neighbor element
Mesh entities of codimension 0 ("elements") allow to visit all neighbors, where a neighbor is an entity of codimension 0 which has a common entity of codimension 1 These neighbors are accessed via a IntersectionIterator. This allows the implement non-matching meshes. The number of neighbors may be different from the number of an element!

Member Function Documentation
◆ boundary()
|
inline |
return true if intersection is with boundary.
◆ boundarySegmentIndex()
|
inline |
return the boundary segment index
◆ centerUnitOuterNormal()
|
inline |
Return unit outer normal (length == 1)
The returned vector is the normal at the center() of the intersection's geometry. It is scaled to have unit length.
◆ conforming()
|
inline |
Return true if this is a conforming intersection.
◆ equals()
|
inline |
◆ geometry()
|
inline |
intersection of codimension 1 of this neighbor with element where iteration started. Here returned element is in GLOBAL coordinates of the element where iteration started.
◆ geometryInInside()
|
inline |
intersection of codimension 1 of this neighbor with element where iteration started. Here returned element is in LOCAL coordinates of the element where iteration started.
◆ geometryInOutside()
|
inline |
intersection of codimension 1 of this neighbor with element where iteration started. Here returned element is in LOCAL coordinates of neighbor
◆ indexInInside()
|
inline |
local number of codim 1 entity in self where intersection is contained in
◆ indexInOutside()
|
inline |
local number of codim 1 entity in neighbor where intersection is contained
◆ inside()
|
inline |
◆ integrationOuterNormal()
|
inline |
return outer normal multiplied by the integration element
◆ neighbor()
|
inline |
return true if across the edge an neighbor on this level exists
◆ outerNormal()
|
inline |
return outer normal
◆ outside()
|
inline |
◆ type()
|
inline |
Geometry type of an intersection.
◆ unitOuterNormal()
|
inline |
return unit outer normal
