Abstract

The rise of supercomputing technologies during the last decade has enabled significant progress towards the invention of a personal biologically relevant computer model of a human heart. In this paper we present a new code for numerical simulation of cardiac electrophysiology on supercomputers. Having constructed a personal segmented tetrahedral grid of the human heart based on a tomogram, we solve the bidomain equations of cardiac electrophysiology using the finite element method thus achieving the goal of modeling of the action potential propagation in heart. Flexible object-oriented architecture of the software allows us to expand its capabilities by using relevant cell models, preconditioners and numerical methods for solving SLAEs. The results of numerical modeling of heart under normal conditions as well as a number of simulated pathologies are in a good agreement with theoretical expectations. The software achieves at least 75% scaling efficiency on the 120 ranks on the Lobachevsky supercomputer.
