Public Attributes
T *	val
	Function values. If T == Hermes::Ord and orders vary with direction, this returns max(h_order, v_order).
T *	dx
T *	dy
	First-order partial derivatives.
T *	laplace
	Sum of second-order partial derivatives. Enabled by defining H2D_USE_SECOND_DERIVATIVES in h2d_common.h.
T *	val0
T *	val1
	Components of a vector field.
T *	dx0
T *	dx1
	Components of the gradient of a vector field.
T *	dy0
T *	dy1
	Components of the gradient of a vector field.
T *	curl
	Components of the curl of a vector field.
T *	div
	Components of the div of a vector field.

Detailed Description

template<typename T>
class Hermes::Hermes2D::Func< T >

Calculated function values (from the class Function) on an element for assembling.

Constructor & Destructor Documentation

template<typename T >

Hermes::Hermes2D::Func< T >::Func	(	int	num_gip,
		int	num_comps
	)

Constructor.

Parameters

[in]	num_gip	A number of integration points.
[in]	num_comps	A number of components.

Definition at line 27 of file forms.cpp.

template<typename T>

virtual Hermes::Hermes2D::Func< T >::~Func ( )

inlinevirtual

All deallocation done via free_fn / free_ord. This is to allow proper destruction of DiscontinuousFunc by applying delete on a Func pointer. NOTE: An error is raised if the user tries to use a Func object for a discontinuous function. Alternatively, both Func::get_*_central and Func::get_*_neighbor could return the central values as expected from a continuous function.

Member Function Documentation

template<typename T>

void Hermes::Hermes2D::Func< T >::add ( Func< T > *  func )

protected

Calculate this += func for each function expations and each integration point.

Parameters

[in]

func

A function which is added to *this. A number of integratioN points and a number of component has to match.

Definition at line 90 of file forms.cpp.

template<typename T>

void Hermes::Hermes2D::Func< T >::subtract ( T *  attribute, T *  other_attribute  )

protected

Parameters

[in]

func

A function which is subtracted from *this. A number of integratioN points and a number of component has to match.
