Simulating Cardiac Electrophysiology Using Unstructured All-Hexahedra Spectral Elements
We discuss the application of the spectral element method to the monodomain and bidomain equations describing propagation of cardiac action potential. Models of cardiac electrophysiology consist of a system of partial differential equations coupled with a system of ordinary differential equations representing cell membrane dynamics. The solution of these equations requires solving multiple leng...
متن کاملSimulating Human Cardiac Electrophysiology on Clinical Time-Scales
In this study, the feasibility of conducting in silico experiments in near-realtime with anatomically realistic, biophysically detailed models of human cardiac electrophysiology is demonstrated using a current national high-performance computing facility. The required performance is achieved by integrating and optimizing load balancing and parallel I/O, which lead to strongly scalable simulatio...

متن کاملFoiwiation of Pyramid Elements for Hexahedra to Tetrahedral Transitions
New algorithms are proposed for the modification of a mixed hexahedra-tetrahedra element mesh to maintain compatibility by the insertion of pyramid elements. Several methods for generation of the p+yramidsare presented involving local tetrahedral transformations and’or node insertion near the he.titet interface. Local smoothing and topological operations improve the quality of the transition re...
متن کاملPseudo-conforming Polynomial Lagrange Finite Elements on Quadrilaterals and Hexahedra
The aim of this paper is to develop a new class of finite elements on quadrilaterals and hexahedra. The degrees of freedom are the values at the vertices and the approximation is polynomial on each element K. In general, with this kind of finite elements, the resolution of second order elliptic problems leads to non-conforming approximations.Degrees of freedom are the same than those of isopara...
