Constructor & Destructor Documentation

Linear2d()

linearFEM::Linear2d::Linear2d	(	concepts::Mesh2 &	msh,
		uint	level,
		concepts::BoundaryConditions *	bc = 0
	)

Constructor.

Parameters

msh	Mesh
level	Number levels for initial refinement
bc	Boundary conditions

Member Function Documentation

adjust()

void linearFEM::Linear2d::adjust	(	const Quad &	elm,
		const short	level
	)

Adjusts an element in the space. Only quads have S matrices, therefore, only quads can be refined.

Parameters

elm	Element to refine
level	Number of refinements

dim()

virtual uint linearFEM::Linear2d::dim ( ) const

inlinevirtual

Returns the dimension of the space.

Implements concepts::Space< Real >.

Definition at line 58 of file space2D.hh.

getOutputDimension()

virtual uint concepts::Space< Real >::getOutputDimension ( ) const

inlinevirtualinherited

Returns the default output dimension, when we consider plotting a real-valued operator on this space.

Definition at line 50 of file space.hh.

info()

virtual std::ostream & linearFEM::Linear2d::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::Space< Real >.

nelm()

virtual uint linearFEM::Linear2d::nelm ( ) const

inlinevirtual

Returns the number of elements in the space.

Implements concepts::Space< Real >.

Definition at line 59 of file space2D.hh.

S()

const SMap & linearFEM::Linear2d::S

(

uint

i

)

const

Returns the ith S matrix. The S matrices are used for the irregular refinement of a mesh. An S matrix is independent of the geometry but it depends on the topological relation of the children with the parent: the bottom left child has a different S matrix than the top right etc.

scan()

virtual Scan * linearFEM::Linear2d::scan ( ) const

virtual

Returns a scanner to iterate over the elements of the space.

Implements concepts::Space< Real >.
