Detailed Description

template<unsigned SPACE_DIM>
class ExtendedBidomainTissue< SPACE_DIM >

Class that provides functionalities to specify a tissue within the context of the extended bidomain framework.

The extended bidomain equations are of the form:

  • div ( sigma_i1 grad Phi_1 ) + Am1*Cm1*d(phi_1)/dt - Am2*Cm2*d(phi_e)/dt + Am1*I_ion1 - Am1*I_stim1 + Amgap*G_gap*(phi_1 - phi_2)

  • div ( sigma_i2 grad Phi_2 ) + Am2*Cm2*d(phi_2)/dt - Am2*Cm2*d(phi_e)/dt + Am2*I_ion2 - Am2*I_stim2 - Amgap*G_gap*(phi_1 - phi_2) div ( sigma_e grad Phi_e ) + div ( sigma_i1 grad Phi_1 ) + div ( sigma_i2 grad Phi_2 ) = I_stim

    The unknowns are:

    • Phi_1 (intracellular potential of the first cell).
    • Phi_2 (intracellular potential of the second cell).
    • Phi_e (extracellular potential).

    Am1, Am2 and Amgap are surface-to-volume ratios for first cell, second cell and gap junction. User can set their values. Cm1 and cm2 are capaciatnce values of first and second cell respectively sigma_i1 and sigma_i2 are intracellular conductivity tensors of first and second cell respectively sigma_e is the conductivity tensor for the extracellular space G_gap is the conductance (in ms/cm2) of the gap junction channel.

Create the pattern of Ggap across the mesh based upon mCellHeterogeneityRegions, mGgapValues and mGgap. This will fill in mGgapDistributed. It will set mGgap everywhere except in the areas mCellHeterogeneityRegions[i] where it will put mGgapValues[i] instead. If mCellHeterogeneityRegions (and mGgapValues) are empty, mGgap will be set everywhere.
