In this paper, we present the four points Explicit
Group (EG) and Explicit Decoupled Group (EDG) schemes for
solving the two dimensional convection-diffusion equation with initial and Dirichlet boundary conditions. The EG method is derived from the centred difference approximation whilst EDG is derived from the rotated difference operator expressed in coordinates rotated 450 with respect to the standard mesh.These new formulations are shown to be unconditionally stable and the robustness of these new formulations over the existing point Crank-Nicolson scheme demonstrated through numerical experiments.
