Member Function Documentation

base()

template<class FV , unsigned int spacedim>

const FV & FEValuesViews::Tensor< FV, spacedim >::base

Returns the FEValues class.

Definition at line 137 of file fe_values_views.cc.

derivative()

template<class FV , unsigned int spacedim>

arma::mat::fixed< spacedim, spacedim > FEValuesViews::Tensor< FV, spacedim >::derivative	(	unsigned int	variable_no,
		unsigned int	function_no,
		unsigned int	point_no
	)		const

Return partial derivative of tensor-valued shape function.

Parameters

variable_no	Index of spacial variable w.r. to which we differentiate.
function_no	Index of shape function within the FE.
point_no	Index of quadrature point.

Definition at line 110 of file fe_values_views.cc.

divergence()

template<class FV , unsigned int spacedim>

arma::vec::fixed< spacedim > FEValuesViews::Tensor< FV, spacedim >::divergence	(	unsigned int	function_no,
		unsigned int	point_no
	)		const

Return divergence of tensor-valued shape function.

The result is a vector whose components are divergences of tensor columns, i.e. (div T)_i = dT_ji / dx_j.

Parameters

function_no	Index of shape function within the FE.
point_no	Index of quadrature point.

Definition at line 125 of file fe_values_views.cc.

value()

template<class FV , unsigned int spacedim>

arma::mat::fixed< spacedim, spacedim > FEValuesViews::Tensor< FV, spacedim >::value	(	unsigned int	function_no,
		unsigned int	point_no
	)		const

Return value of tensor-valued shape function.

Parameters

function_no	Index of shape function within the FE.
point_no	Index of quadrature point.

Definition at line 99 of file fe_values_views.cc.
