Hey Foamers
I need a little guidance with the numerical schemes for the convection term: I'm solving Turbulent flow past a cube in a channel using LES models and used Upwind and QUICK schemes, however they are very dissipative. Has anyone used kinetic energy conservative schemes in OF? thanks in advance. |

For LES, the recommended scheme is "linear" (or a higher-order central scheme). Of course you need a mesh that satisfies the stability criterion of this scheme.
Best,
