May 25, 2018, 12:33	Choosing the suitable number of time steps	#1
bmaicuong New Member Join Date: May 2018 Posts: 12 Rep Power: 8	Hi everybody, I am very new in Fluent and I have some problems when using this software to do my thesis. Please give me some advice. I am simulating the flow over a solid sphere and find the drag coefficients on sphere wall, using transient modeling. The radius of sphere is 1m, the length of computational domain is 25m and the sphere is located at 10m from the inlet. The flow velocity is estimated at 2.5m/s. Based on CFL, I choose the time steps as 0.01s. Please help me choose number of time steps so that Fluent can give me the best results. Many thanks in advance. Sorry for my bad English.
