Detailed Description

template<class T>
class Galeri::FiniteElements::GalerkinVariational< T >

Defines a pure Galerkin variational form of a scalar PDE.

This class defines a pure Galerkin variational form of a second order, symmetric scalar PDE, discretized using Lagrange finite elements. The class is templated with an AbstractQuadrature class, which will be used to specify the quadrature formula, and the values of test and basis functions at the quadrature node. The constructor requires function pointers, that specify the values of the coefficients.
