hello,
"nutLowReWallFunction" is described in OF-Doxygen as: -------------------------------------------------------------------------------------- This boundary condition provides a turbulent kinematic viscosity condition for use with low Reynolds number models. It sets nut to zero, and provides an access function to calculate y+. -------------------------------------------------------------------------------------- As guessed: now, OF's low_Reynolds_number_models can act as low or high Re models according to the cell-location off the wall, then my question is, what does "It sets nut to zero" mean? (since it doesn't make sense, that nut is set to zero) thank you in advance |
