It makes use of a local coefficient. In my model it works quite well, better than the dynamic Smagorinsky. Do you know wether it is implemented properly?

Ok, I understand why upwind schemes are not a good idea for LES. What about usind a TVD Scheme like limitedlinear which is less dissipative but more stable then cds? I have found several papers that...

The geometry, which is shown in the above pictures, was meshed with blockMesh. So I have a fully hex mesh here. With this geometry I don't have any convergence problems at all. The complex geometry...

When I use the oneEqEddy Model I get rather high nuSGS (O(10e-6)) and so too much dissipation. When using the dynamic Smagorinsky Model I get much higher nuSGS (O(10e-8)). The...
