shape_values

template<class PolynomialType , int dim, int spacedim = dim>

std::vector<std::vector<Tensor<1, dim> > > FE_DGVector< PolynomialType, 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. Since the shape functions are vector-valued (with as many components as there are space dimensions), the value is a tensor.

In this array, we store the values of the shape function in the quadrature points on the unit cell. The transformation to the real space cell is then simply done by multiplication with the Jacobian of the mapping.

shape_gradients

template<class PolynomialType , int dim, int spacedim = dim>

std::vector<std::vector<Tensor<2, dim> > > FE_DGVector< PolynomialType, 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.
