Yes, at the end of any simulation the URF's should always be as high as possible. That is because at the end of the simulation, your solution should be the solution. If your solution blows up, then...

Depending on the grid and scheme used, it is very possible, for all your solution values to be converged to very high accuracy but residuals to still be decreasing for many many iterations after. As...

That means same grid, same settings, same everything but under-relaxation factors. On the same note, once the residuals reach constant, with...

Unless your solution is diverging, do not bother with the under-relaxation factors. If it is diverging, do as you did, lower the factors until you can...
