Title: Adaptive immersed boundary methods for simulating cardiac mechanics and electrophysiology

Abstract:

Although the equations that describe cardiac mechanics and electrophysiology are different, in both cases a realistic treatment demands the use of methods that account for anisotropy, inhomogeneity, and complex geometries. Moreover, although it may appear that substantially different approaches are required to simulate cardiac mechanics and electrophysiology, we employ a unified theoretical framework, the immersed boundary (IB) method, for both aspects of cardiac physiology. This unified approach to modeling and simulating cardiac physiology not only yields methodological overlap but also allows for substantial software reuse.

This talk will include an overview of an adaptive version of the IB method for problems of fluid-structure interaction, as well as results obtained from the application of this adaptive methodology to the three-dimensional simulation of blood flow in the heart. I shall also discuss the application of the IB framework to the simulation of cardiac electrophysiology. Basic details of cardiac physiology will be introduced as necessary.
