Residual? -- CFD Online Discussion Forums

May 29, 2007, 07:38	Residual?	#1
Beginner Guest Posts: n/a	Hi, I would like to have an idea about formulas for calculating the residual over a domain with uniform grid to fix the convergence criteria. Usually I use (Finite difference scheme): res = sqrt((Un+1-Un)^2/N) where N is the number of nodes. Is it correct???
