Dear Mathias, rnrnWhat should I do to deal with such a situation. I have chosen the “”MRTdynamic”” which should reflect the turbulent property. Is it possible to chose a smaller Umax or higher resolution in order to get the stable velocity distribution when the flow get into the turbulent zone.rnrnThe distribution of Posseuille flow before unstable is bimodal distribution which is not the exactly turbulent flow velocity distribution.rnrnthanks a lot rnrnJepson
