Detailed Description

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

Simple implementation of AbstractFeVolumeIntegralAssembler which provides the volume part of the Monodomain mass matrix for a given mesh, multiplied by a scale factor if required. In other words, the matrix If N is the space dimension, we compute the Matrix M (2N,2N) where

M_{ij} = k integral_{domain} phi_i(x) phi_j(x) dV, if i<N and j<N,

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

M_{i,j}= 0, if i>=N or j>=N;
