Hi everyone, I am studying flow past a cylinder for laminar flow(reynold's no=500).I solved using pisoFoam. My final courant number was 1.8.Is it correct? Also i want to plot co-efficient of drag, lift, Cm. How can i do so using paraview??? plz help. Thanks Subhankar
Dear Subhankar, Courant number is used to maintain stability of the solution and avoid divergence. Courant number should be less than one. So a Courant number of 1.8 seems to be incorrect. You can use Gnuplot / Libre Spreadsheet to plot Lift and Drag co-efficients. You need not use Paraview for plotting them. Regards
Thanks for the quick reply...Can u tell me what changes i could make to make my courant no less than 1?
