turbulent viscosity ratio for atmospheric boundary layer(ABL)
 
the turbulent viscosity ratio(TVR) for the atmospheric boundary layer(ABL) is in the order of 10⁶ and height over 200m is around 10⁷, if K-w SST turbulent model. the general limit for TVR is 10⁵ in the solvers. Is it good to increase the limit of TVR to 10⁷ or stick to default limit?
