Web3 de set. de 2014 · Under-relaxation is used, when your new values x_i+1 tend to be even worse than the old values x_i, since your dx_i was too large. You "jumped" over your target value. It stabilizes the simulation but generally makes it slower. Under-relaxation for SIMPLE algorithm are normally about the values I proposed in my post.
