Detailed Description

class BidomainMatrixBasedAssembler< ELEMENT_DIM, SPACE_DIM >

BidomainMatrixBasedAssembler

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 bidomain problem, B is the mass matrix for 2 unknowns (see BidomainRhsMatrixAssembler) ***IF*** the unknowns were ordered [V1 V2 .. V_N phi_e1 ... phi_eN ], then z would be

z = [z1] [z2] where z1 = CA V^{m}/dt - A I_ionic - Istim_intra and z2 = -Istim_extra,

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).
