Member Function Documentation
◆ base()
| const FEValues< spacedim > & FEValuesViews::Tensor< spacedim >::base |
Returns the FEValues class.
Definition at line 137 of file fe_values_views.cc.
◆ derivative()
| 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_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()
| 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_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()
| 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_no Index of shape function within the FE. point_no Index of quadrature point.
