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!
◆ centerUnitOuterNormal()
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.
◆ geometry()
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()
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()
intersection of codimension 1 of this neighbor with element where iteration started. Here returned element is in LOCAL coordinates of neighbor
◆ inside()
return Entity on the inside of this intersection (that is the Entity where we started this Iterator)
◆ outside()
return Entity on the outside of this intersection (that is the neighboring Entity)
