Detailed Description

template<size_t NF>
class P13DTrace< NF >

Traces of P13DElement.

These trace elements are templated according to the number of linear fields and the Tetrahedron face P13DTrace<NF>::FaceLabel on which the trace is computed.

Traces of P13DElements are somewhat special, since for each side one of the bulk basis functions is identically zero, effectively leaving three dofs per face. To reduce the amount of memory allocated per element is then convenient to consider trace elements with only 3 dofs per field per face, i.e., use the ShapesP13D::Faces ShapesEvaluated objects.

However, ocassionally, it may be necessary to have the boundary elements have the same nummber of dofs as the bulk elements, as it is generally the case for arbitrary bases. Hence during their construction, it is possible to specify what type of shape functions to use. This is accomplished by specifying the type ShapeType.

Warning:

As opposed to P13DElement(s), there is no local copy of the geometry of the element here, but only a reference to it. Hence, the destruction of the base geometry before the destruction of the element will render the implementation inconsistent.

Todo:

As was commented in P12DTrace, TetGeom may have to be a pointer and not a reference, since this is a reference to a copy of the original geometry.
