UV_SMAGORINSKY

#1 Unread post by shifei »

Hi,
I try to use biharmonic mixing of momentum (UV_VIS4) with UV_SMAGORINSKY. It always blow up quickly, even I shorten the time step.
And ROMS give messeage like:
CHECKADJ - use caution when activating: UV_SMAGORINSKY
REASON: stability problems, WARNING.

What's meaning of UV_SMAGORINSKY. What should I be careful about with UV_SMAGORINSKY.
