摘要: Recently, the authors presented difierent block preconditioners for implicit Runge-Kutta discretization of heat equation. The were Jacobi and Gauss-Seidel preconditoners where blocks reused existing Euler same In this paper we will introduce similar Bidomain We will, by numerical experiments, show properties preconditon- ers, that higher-order equation may be superior to lower-order in some cases.
