Anna Tian Senior Member Meimei Wang Join Date: Jul 2012 Posts: 494 Rep Power: 15	Hi, May I ask how to decide how many grid lines(at the direction proportional to the wall) do I need(to resolve boundary layer well)? Of course grid independence study is always good practice. But I always need a first guess of this number to have my first grids before the grid independence study. Thank you very much. immortality likes this. __________________ Best regards, Meimei
