HakikiCanakkaleli Senior Member Canakkale Dardanelspor Join Date: Aug 2012 Posts: 135 Rep Power: 13	Hi, == 1 == Could someone please explain what the main difference of using "bounded" keyword result in? Code: divSchemes { ... div(phi,U) bounded Gauss linearUpwind grad(U); ... } Code: divSchemes { ... div(phi,U) Gauss linearUpwind grad(U); ... } == 2 == In Table 4.10 of http://www.openfoam.org/docs/user/fvSchemes.php, it is stated that 'linearUpwind' is 'bounded'. Despite this, why do we need to add 'bounded' keyword to the scheme arguments? ==3== Many thanks in advance.
