Constructor & Destructor Documentation

ShapeFunction::ShapeFunction

(

Shapeset *

shapeset

)

Constructs a standard precalculated shapeset class.

Parameters:

shapeset

[in] Pointer to the shapeset to be precalculated.

ShapeFunction::ShapeFunction

(

)

ShapeFunction::~ShapeFunction

(

)

[virtual]

Destructor.

Member Function Documentation

void ShapeFunction::force_transform	(	uint64	sub_idx,
		Trf *	ctm
	)			[inline, protected]

index of active shape function

Forces a transform without using push_transform() etc. Used by the Solution class. For internal use only.

Reimplemented from Function< TYPE >.

void ShapeFunction::free

(

)

[virtual]

Frees all precalculated tables.

Implements Function< TYPE >.

int ShapeFunction::get_active_shape

(

)

const [inline]

Returns:

Index of the active shape (can be negative if the shape is constrained).

Shapeset* ShapeFunction::get_shapeset

(

)

const [inline]

Returns:

Pointer to the shapeset which is being precalculated.

ESpaceType ShapeFunction::get_type

(

)

[inline]

void ShapeFunction::precalculate	(	const int	np,
		const QuadPt3D *	pt,
		int	mask
	)			[virtual]

precalculates the current function at the current integration points.

Implements Function< TYPE >.

void ShapeFunction::set_active_element

(

Element *

e

)

[virtual]

Ensures subsequent calls to get_active_element() will be returning 'e'. Switches the class to the appropriate mode (triangle, quad).

Reimplemented from Transformable.

void ShapeFunction::set_active_shape

(

int

index

)

Activates a shape function given by its index. The values of the shape function can then be obtained by setting the required integration rule order by calling set_quad_order() and after that calling get_values(), get_dx_values(), etc.

Parameters:

index

[in] Shape index.

void ShapeFunction::set_shapeset

(

Shapeset *

ss

)

void ShapeFunction::set_transform

(

ShapeFunction *

shfn

)
