Hi Foamers,

I am looking for a 2nd order accurate (theoretical order of accuracy) discretization scheme for convection terms that is found to do nice job in a case of fluid flow with recirculation (e.g. sudden expansion/contraction flow, flow past square/circular cylinders etc.) Any suggestions? I was thinking about MinMod... Somewhere on OF forum I have read that LinearUpwind scheme as implemented in OF is actually not 2nd order accurate - is that true?
