Detailed Description

template<unsigned int spacedim = 3>
class FEValuesViews::Tensor< spacedim >

Definition at line 126 of file fe_values_views.hh.

Constructor & Destructor Documentation

◆ Tensor()

template<unsigned int spacedim = 3>
FEValuesViews::Tensor< spacedim >::Tensor ( const FEValues< spacedim > &  fe_values,
unsigned int  component 
)
inline

Definition at line 130 of file fe_values_views.hh.

Member Function Documentation

◆ base()

template<unsigned int spacedim>
const FEValues< spacedim > & FEValuesViews::Tensor< spacedim >::base

Returns the FEValues class.

Definition at line 137 of file fe_values_views.cc.

◆ derivative()

template<unsigned int spacedim>
arma::mat::fixed< spacedim, spacedim > FEValuesViews::Tensor< 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_noIndex of spacial variable w.r. to which we differentiate.
function_noIndex of shape function within the FE.
point_noIndex of quadrature point.

Definition at line 110 of file fe_values_views.cc.

◆ divergence()

template<unsigned int spacedim>
arma::vec::fixed< spacedim > FEValuesViews::Tensor< 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_noIndex of shape function within the FE.
point_noIndex of quadrature point.

Definition at line 125 of file fe_values_views.cc.

◆ value()

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

Return value of tensor-valued shape function.

Parameters
function_noIndex of shape function within the FE.
point_noIndex of quadrature point.

Definition at line 99 of file fe_values_views.cc.
