Turbulence model for subsea stability, Pls.
 

Hi, I am doing an M.sc research using CFD to analyse the stability of a concrete structure laid on the sea bed. What turbulence model is recommended for this envirnment pls. I have tried K-E model but my drag and lift coefficients are very small (0.1 and 0.2). am not sure if this is realistic. Also tried RNG model but i did not get a convergence.

Any suggestions pls.
