Alternating group explicit method with exponential-type for the diffusion-convection equation. (English) Zbl 1114.65100
Summary: Based on the semi-explicit asymmetric exponential schemes, a new alternating group explicit method with exponential-type for the numerical solution of the convection-diffusion equation is derived. The method has the obvious property of parallelism and is unconditionally stable. The results of numerical examples are given to show the effectiveness of the present methods that are in preference to the method of D. J. Evans and A. R. Abdullah [Comput. Math. Appl. 11, 145–154 (1985; Zbl 0579.65094)].
