Detailed Description

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

Implementation of AbstractFeVolumeIntegralAssembler which provides stiffness matrices required in monodomain problems:

K_{ij} = integral_{domain} grad_phi_i(x)^T (sigma * grad_phi_j(x)) dV

where phi_i is the i-th (linear) basis function
