A. Salsi et al., Numerical approximation of reaction-diffusion problems in electrocardiology using probabilistic methods, MATH COMP M, 31(4-5), 2000, pp. 181-188
We present a grid-free numerical method to solve reaction-diffusion problem
s in two-dimensional bounded domains, based on the combination of stochasti
c and deterministic techniques. A gradient random walk models the diffusion
, and the reaction term involves deterministic growth or decay of particles
. The application to the simulation of the cardiac potential evolution in a
model of cardiac tissue is shown. (C) 2000 Elsevier Science Ltd. All right
