Dewson Guest Posts: n/a	I want to simulate single gas-phase by considering the friction factor. Now the questions are: (1) when selecting the 'Laminar' viscous model, I amnot sure whether it including the fraction fractor or not? According to the UG manual, it is not clear to me. (2) If I want to incorporate the UDF friction factor, how can I do? My geometry is simple cylinder pipe. Please help me out.
