Hi All,

I was wondering if there exists an exact stability analysis of pressure-based schemes, like say, SIMPLE? Since most commercial solvers have (one form or the other) pressure-based solvers like SIMPLE (-C, -R), PISO etc... is there any guide line of the CFL or time-step for these solvers, that comes from an analysis of the pressure-based scheme in itself and not model equations like the wave equation or burgers equation.

Any insight is much appreciated!
