Abstract
In this paper, a new three-level explicit difference scheme with high- order accuracy is proposed for solving three-dimensional parabolic equ ations. The stability condition is r = Delta t/Delta x(2) = Delta t/De lta gamma(2) = Delta t/Delta z(2) less than or equal to 1/4, and the t runcation error is O(Delta t(2) + Delta x(4)).
