Step size for sliding mesh... -- CFD Online Discussion Forums

April 4, 2000, 09:41	Step size for sliding mesh...	#1
Jack Keays Guest Posts: n/a	Hi, I am running a 2d simulation of a centrifugal pump. The flow is unsteady and I am using a sliding mesh technique. Would be a good idea to use the MRF in Fluent to get an initial guess and then continue from there with the sliding mesh?? ALso, what would be considered an intelligent step size? Does anyone know of any article/paper dealing with this? I am currently using 15 degrees. Probably too large. I hope someone can help me, Jack.
