Hello rwoolhou,


Honestly, I do not get it. I have calculated the Reynolds number in each part of the pipe and I know according to Reynolds number equation, Re should decrease as there's a sudden decrement of diameter. Should I manually and separately set the first layer cell height according to the diameter of pipes which are 206 and 102 mm respectively or not, therefore the first layer cell height for all parts of my pipe system are the same?
