Take the jump between the trace from side in which the normal vector points and the other side.
Definition at line 150 of file edge.hh.
Returns the element and the geometrical cell as pair belonging to the k
th edge in the quadrilateral element elm
. The polynomial degree and the T matrix are set properly.
The geometrical cell is included in the element as reference, so it has to be deleted after deletion of the element.
If edge
is given than degrees of freedom are added by adapting the T-matrix. This is the case when taking trace from both sides of an edge (e.g., mean or jump). In that case the cell is not returned in the pair, i.e., the returned pointer to the cell (Edge2d) is 0.

emptyElm | Incorporate also empty elements (no dof). |
edge | Element to which dof are added (adaptation of T-matrix) |
