const FEValues< spacedim > & FEValuesViews::Tensor< spacedim >::base |
Returns the FEValues class.

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

unsigned int | point_no | ||
) | const |
Return value of tensor-valued shape function.
function_no | Index of shape function within the FE. |
point_no | Index of quadrature point. |
