Acceptable Gradient Values -- CFD Online Discussion Forums

January 12, 2005, 18:00	Acceptable Gradient Values	#1
Raman Chadha Guest Posts: n/a	Hi, I am solving a turbulent flow problem using RNG k-e model. I want to show grid independence using grid adaption. How do we ascertain if the maximum gradient values are "good enough", and does adaption always work? I am having trouble showing grid independence for the solution. What are the general guidelines for showing grid independence for the solution.
