Detailed Description

template<unsigned int dim, unsigned int spacedim>
class FESideValues< dim, spacedim >

Calculates finite element data on a side.

FESideValues takes care of the calculation of finite element data on a side of the actual cell such as values of shape functions at quadrature points, gradients of shape functions, Jacobians of the mapping from the reference cell etc.

Parameters

dim	Dimension of the reference cell.
spacedim	Dimension of the Euclidean space where the actual cell lives.
