Detailed Description

A 2D cell: infinite rectangle.

If a infinite rectangle is subdivided, two new infinite infinite rectangles are created. This happens automatically, if a child is requested

Member Function Documentation

Real3d concepts::InfiniteRect2d::center

(

)

const [virtual]

Makes no sense. Calling throws an exception.

Implements concepts::Cell2.

virtual Real2d concepts::InfiniteRect2d::chi	(	Real	xi,
		Real	eta
	)		const [virtual]

Evaluates the element map.

Maps a point from the the reference coordinates in [0,1]^[0,) onto the physical coordinates.

Returns:

Point in 2D in physical coordinates.

Parameters:

xi
eta

Implements concepts::InfiniteQuad2d.

virtual InfiniteRect2d* concepts::InfiniteRect2d::child

(

uint

i

)

[virtual]

Returns a child.

If no children exist, four new children are created. The quadrilateral is cut into four new quadrilaterals by joining the midpoints of its edges.

Parameters:

i	Index of the child to be returned.

Implements concepts::Cell2.

virtual const InfiniteRect2d* concepts::InfiniteRect2d::child

(

uint

i

)

const [virtual]

Returns a child.

If no children exist, none are created and 0 is returned.

Parameters:

i	Index of the child to be returned.

Implements concepts::Cell2.

InfiniteRect2d* concepts::InfiniteRect2d::clone	(	InfiniteQuad &	cntr,
		const Real2d &	vtx0,
		const Real2d &	vtx1
	)		const [inline]

Returns a copy of itself.
