Detailed Description

template<int dim, int spacedim = dim>
struct FEValuesViews::Scalar< dim, spacedim >::ShapeFunctionData

A structure where for each shape function we pre-compute a bunch of data that will make later accesses much cheaper.

Member Data Documentation

template<int dim, int spacedim = dim>
bool FEValuesViews::Scalar< dim, spacedim >::ShapeFunctionData::is_nonzero_shape_function_component

For each shape function, store whether the selected vector component may be nonzero. For primitive shape functions we know for sure whether a certain scalar component of a given shape function is nonzero, whereas for non-primitive shape functions this may not be entirely clear (e.g. for RT elements it depends on the shape of a cell).

template<int dim, int spacedim = dim>
unsigned int FEValuesViews::Scalar< dim, spacedim >::ShapeFunctionData::row_index

For each shape function, store the row index within the shape_values, shape_gradients, and shape_hessians tables (the column index is the quadrature point index). If the shape function is primitive, then we can get this information from the shape_function_to_row_table of the FEValues object; otherwise, we have to work a bit harder to compute this information.
