Dear all,

This issue was already discussed in some length in various threads. Therefore I finally reviewed and attached my plusPostRANS utility.

It calculates y+ and u+ values when using one of the available low-Re RANS turbulence models. I hope the code as well as the output will be self-explaining

I also attached a case. It is a straight pipe (wedge) with periodic inlet/outlet boundary conditions. The Reynolds number based on the mean axial velocity is Re=5300. You can run the case using pisoFoam.

I would appreciate any feedback, it might be still improved at some point!

Best regards,
Florian
