Hi Eli I tried to do low-Re in a geometry like shock tube but it took a lot of time in compare to high-Re and I stopped that!because I found out that I didn't need that much accuracy near the walls....

Replies: 16 defining of turbulence coefficient boundary condition on the wall Views: 2,269 Posted By immortality defining of turbulence coefficient boundary condition on the wall hi How can set k-omega or epsilon on the wall? How can find out what values should be put on the wall? I have seen some inlet flow BC explanation and formula in the net but how is it defined on...
