Approximation of yplus

December 9, 2002, 07:01

Dear all,

I will use the v2f turbulence model together with Fluent 6. My question: is there a simple way to approximate yplus, when the geometry, the main flow velocity and the distance of the first grid point from the wall is known, without doing the whole grid generation and a simulation ?

Thank you very much in advance for your answers.

Best regards

Frank
