Hello everyone, I was wondering if anybody has done any grid sensitivity on a channel for any Laminar Re number; specifically Re=100? I have a simple channel with an inlet of a given velocity and outlet, and my vertical lines are stretched to give me a more accurate reading of the velocity profile near the walls. If anyone has, how many vertical and horizontal lines did you use for an accurate result and how did you go about finding the correct line numbers? Kyle If a command file is necessary let me know and I will provide one.
