LES tutorial for pitzDaily
 
Hello,
I am running the LES tutorial for pitzDaily with pisoFoam in 1.6.x. I have already run this case with kEpsilon model in simpleFoam. the results from simpleFoam is in good agreement in experiemntal data. but the LES fails to recover the experimental data. I found the k (turbulent kinematic energy is 2e-5 in pisoFoam, and 0.375 in simpleFoam) and the endtime is 0.1, much shorter than that in simpleFoam. Is it 0.1 too short to get converged? Any one who sucessfully run this tutorials, give me some hits.

Thanks
