Detailed Description

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

MonodomainMatrixBasedAssembler

This class makes use of the functionality in its parent, AbstractDynamicAssemblerMixin, for specifying a constant matrix B and time-dependent vector z such that the finite element RHS vector b (in Ax=b) satisfies Bz=b, and therefore b can be constructed very quickly each timestep (compared to looping over elements and assembling it.

For the monodomain problem, B is the mass matrix (see MonodomainRhsMatrixAssembler) and z = CA V^{m}/dt - A I_ionic - Istim where V is the vector of voltages are the last timestep, and I_ionic and I_stim are nodewise vectors of ionic currents and stimulus currents (and C is the capacitance and A surface-area-to-volume ratio).
