Detailed Description

A model for cardiac conduction.

Base model of cardiac electrophysiology of the form

$\begin{align*} \frac{\partial u}{\partial t} = \nabla^2 u + J_{ion}, \end{align*}$

where the reaction term, $J_{ion}$ is defined by a specific cell model.

This implementation, at present, treats the reaction terms explicitly and the diffusive element implicitly.
