Member Function Documentation

clone()

virtual MappingStraightEdge2d * concepts::MappingStraightEdge2d::clone ( ) const

virtual

Virtual copy constructor.

Implements concepts::MappingEdge2d.

curvature()

virtual Real concepts::MappingStraightEdge2d::curvature ( const Real  t, uint  n = 0  ) const

virtual

Returns the n-th derivative of the curvature.

It's implemented in general for n = 0,1 and works with curved edges. Can be overwritten in derived classes for performance reasons.

Reimplemented from concepts::MappingEdge2d.

derivative()

virtual Real2d concepts::MappingStraightEdge2d::derivative ( const Real  t, const uint  n = 1  ) const

virtual

Returns the n-th derivative.

Implements concepts::MappingEdge2d.

info()

virtual std::ostream & concepts::MappingStraightEdge2d::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::MappingEdge2d.

inverse()

virtual MappingStraightEdge2d * concepts::MappingStraightEdge2d::inverse ( ) const

inlinevirtual

Returns the mapping of the edge in inverse direction.

Reimplemented from concepts::MappingEdge2d.

Definition at line 229 of file elementMaps.hh.

n0()

Real2d concepts::MappingEdge2d::n0 ( const Real  t ) const

inlineinherited

Returns the normalised right normal vector.

Definition at line 107 of file elementMaps.hh.

operator()()

virtual Real2d concepts::MappingStraightEdge2d::operator() ( const Real  t ) const

virtual

Application operator. Maps the point from the parameter domain onto the physical space.

Implements concepts::MappingEdge2d.

part()

MappingStraightEdge2d * concepts::MappingStraightEdge2d::part ( const Real  t0, const Real  t1  ) const

virtual

Returns a new object of an element map for a rectangular part of the reference cell defined by the two points.

Reimplemented from concepts::MappingEdge2d.

vtx()

const Real2d & concepts::MappingEdge2d::vtx ( uint  i ) const

inlineinherited

Spit out one vertex of the edge.

Definition at line 124 of file elementMaps.hh.
