An optimum time step length for convergence to steady-state solution in compressible-flow calculations
In making calculations on compressible convection in a closed box (two- dimensional problem for argon at 1 atm.) using the implicit factored scheme given by \textit{R. M. Beam} and \textit{R. F. Warming} [AIAA J. 16, 393-402 (1978; Zbl 0374.76025)], we have found that an optimum value of the time step length exists beyond which the rate of convergence to a steady state decreases rapidly.
