Unconditional Stability in Convection Computations
A theoretical treatment of the numerical properties of a class of explicit schemes of the pure convection equation is presented. The von Neumann and Hirt analyses are used to show that unconditional stability and second-order accuracy are both possible within the framework of an explicit formulation. Three unconditionally stable and second-order accurate explicit schemes are presented. In two of them, the weighing factors vary in time and space as a function of the local Courant number.
