Member Data Documentation

template<class POLY, int dim, int spacedim = dim>
std::vector<std::vector<double> > FE_Poly< POLY, dim, spacedim >::InternalData::shape_values

Array with shape function values in quadrature points. There is one row for each shape function, containing values for each quadrature point.

In this array, we store the values of the shape function in the quadrature points on the unit cell. Since these values do not change under transformation to the real cell, we only need to copy them over when visiting a concrete cell.

template<class POLY, int dim, int spacedim = dim>
std::vector<std::vector<Tensor<1,dim> > > FE_Poly< POLY, dim, spacedim >::InternalData::shape_gradients

Array with shape function gradients in quadrature points. There is one row for each shape function, containing values for each quadrature point.

We store the gradients in the quadrature points on the unit cell. We then only have to apply the transformation (which is a matrix-vector multiplication) when visiting an actual cell.
