This paper presents the Alternating Segment Explicit-Implicit (ASE-I) method forsolving the convection-diffusion equation. The method has the obvious property ofparallelism, and is unconditionally stable. Numerical example is presented.
The well-known AGE(Alternating Group Explicit)method is extended for solv-ing the two-dimensional parabolic with variable coefficients and the unconditional stability of the AGE method is proved by the energy method in the discrete L2-norm.
