Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class MassMatrixAssembler< ELEMENT_DIM, SPACE_DIM >

Simple implementation of AbstractFeVolumeIntegralAssembler which provides mass matrices for a given mesh, multiplied by a scale factor if required. In other words, the matrix

M_{ij} = k integral_{domain} phi_i(x) phi_j(x) dV

where phi_i is the i-th (linear) basis function and k the scale factor (constant throughout the mesh).
