Largescale Numerical Solution of the Cardiac Bidomain Equations
G. Plank (Medical University of Graz, Austria)
Modelling of cardiac arrhythmias based on the bidomain equations has proven to be a powerful method capable of providing insights into arrhythmogenesis and defibrillation.
In recent years, computer models have become increasingly more realistic accounting for details in terms of cellular dynamics and anatomical representation. However, even when employing the most powerful computers available, whole heart simulations over longer observation periods remain computational challenging. This talk will focus on numerical techniques for dealing with the two computationally most burdensome aspects of the bidomain equations: the embedded elliptic PDE and the extremely stiff set of ODEs describing the cellular dynamics.
