Abstract
The bidomain model describes the anisotropic electrical properties of cardiac tissue. One common numerical technique for solving the bidomain equations is the explicit forward Euler method. In this communication we derive a relationship between the time and space steps that ensures the stability of this numerical method.
摘要
双域模型描述了心脏组织的各向异性电学特性。求解双域方程的一种常用数值技术是显式向前欧拉方法。在本通讯中，我们推导了时间步长和空间步长之间的关系，以确保该数值方法的稳定性。
