Hi,
I have a turbulent channel flow with slip BC. on bottom wall and I have solved this channel with channelFoam. I would like to calculate the WallShearStress and also I want to create turbulence fields for calculating the Reynolds stress R, in OpenFoam 1.6. I should be remind that my Turbulence Model is LES. How can I do that?

Regards,
Alireza

Hi idrama

yes, I have used wallShearStress but it didn't work. when I use this term this message appears:

Create time

Create mesh for time = 3.00141

Time = 3.00141
Reading field U

Reading/calculating face flux field phi

Hallo,

wallShearStress is dependent on on turbulence models, hence is need RASProperties. You must check that. Strangely, the time mesh value 3.**.
If you cannot fix it, check the Forum for "computing wall shear stresses", I think. In this Forum, there are already hot discussens about that.

cheers
