Hello I want to use CFX4.3 to model the flow of turbulent regime i.e. water. The geometry consists of a stirred tank reactor with single rushton turbine. Could people suggest me how to go about doing this. Nishant

you would refer to the solver and reference examples. there are similar examles. I suggest you the unmatched and sliding grids(given in 1.2.16 of solver manual). this is most useful when used together with transient gridding to give sliding interface between blocks.(reference example 35 : flow round a cylinder using sliding grids)
