Hi,
Does anyone know the definition of the "nut"? When you choose Spalart-Allmaras turbulence model, one of the residual is "nut". Currently, I guess "nut" is the nu_t, i.e. turbulent kinetic viscosity, but I can't explain why at first iteration its value is alway very small instead of unit 1. I hope someone could help me. Many thanks. |

i also want to this point. the calculation can go when I use k-epsilon model, but when it cann't go further when i use SA or DES with SA as ' Divergence detected in AMG solver: nut'
