[NP] Open Problem for FDM-DGS Solving Navier-Stokes Equation

manual draft Details: momentum equation in N-S solved by FDM-DGS solver seems has faster convergent rate and reaching given precision easier than mass equation. The question is how to balance (1) the loop on G-S smoother for velocity and (2) residual-correction iteration for pressure, and what's their exact relation (i.e. existence of consistent converging ratio). Those can be tested numerically before theoretical works. - Jinghao Chen on Feb 21, 2020
