MESH best guidelines

faisal_durr · October 22, 2012, 07:32

Hello guys,

I wanted to ask about the best practice guide lines for the mesh used. I know for RANS you keep on refining the mesh until you get a mesh independent solution. For LES a best practice is integral length scale/filter width should be about 10. But what about URANS and SAS? What are the best practice meshes for such simulations?

Thanks.
