Sub-iterations - What do they mean? -- CFD Online Discussion Forums

May 18, 2004, 15:37	Sub-iterations - What do they mean?	#1
Arun Guest Posts: n/a	Hi ! I know this is a basic CFD issue. Could someone detail me as to how Sub-iterations in FLuent work? How is the CFL number used to determine timesteps for sub-iterations? Is it okay if convergence does not happen within the maximum number of sub-iterations? What is its impact on the solution at the next physical time step level? It would be happy if anyone could answer any part of this question. Thank you. Arun
