Calculating the yPlus value for SA-model simulation

Siren · February 3, 2012, 07:45

Hello everyone!

I've done a DES-Simulation with an modified Spalart-Allmaras turbulence model wich does not solve the turbulent kinematic Energy "k".

Since I'm interested in the yPlus-values and the standard OpenFOAM tool for the calculation of this value needs the turb. kin. Energy, I wonder if there is a easy solution or tool wich gives me the yPlus-values.

Have a nice day.

P.S.: I'm using 1.7.1 for this.

Hi Siren, there is a tool in openFoam called yPlusLES and another one called yPlusRAS but I did not good results with it and I am writing my own tool for that.
Try the one in OpenFoam, it will be nice to have your feedback.

Have a look at this thread

There is supplied an additional tool for the computation of yPlus.
