Hi, I am doing LES on a locally refined mesh, so I need to smooth delta. I have found that the ratio of deltas between two cells is no larger than a specified amount, typically 1.15, as it says in "smoothDelta.H". But I don't know how to set the parameters in "turbulenceProperties". What is the "maxDeltaRatio" of the smoothCoeffs? Do I need to set this value to 1.15? Thanks
