hi all, iam analysing flow through conical diffuser.since the geometry is subjected to adverse pressure gradient the V2F turbulence model is needed for predicting the flow seperation near wall.so i wouldlike to know whether Fluent6.1 has this model in built or i have to write my UDF for V2F ? looking forward to your answers... regards karunakar.

Look in the manual - it's there, but you'll have to pay special royalty for using it. Anyway, you can use RSM instead and it should be only better with only slight increase in CPU cost.
