A mixed implicit-explicit numerical scheme for integrating the bidomain model of cardiac action potential propagation was faster than a fully explicit scheme with no increase in algorithmic complexity.
A new mixed implicit-explicit numerical scheme improves the computational efficiency of solving bidomain equations for cardiac action potential propagation.
A numerical scheme for efficient integration of the bidomain model of action potential propagation in cardiac tissue is presented. The scheme is a mixed implicit-explicit scheme with no stability time step restrictions and requires that only linear systems of equations be solved at each time step. The method is faster than a fully explicit scheme and there is no increase in algorithmic complexity to use this method instead of a fully explicit method. The speedup factor depends on the timestep size, which can be set solely on the basis of the demands for accuracy. (c) 1998 American Institute of Physics.
Keener et al. (Sun,) conducted a other in Cardiac tissue action potential propagation (computational model). Mixed implicit-explicit numerical scheme vs. Fully explicit scheme was evaluated on Integration speed and algorithmic complexity. A mixed implicit-explicit numerical scheme for integrating the bidomain model of cardiac action potential propagation was faster than a fully explicit scheme with no increase in algorithmic complexity.
