In /home/foam141/OpenFOAM/OpenFOAM-1.4.1/src/LESmodels/incompressible/dynSmagorinsk y/dynSmagorinsky.C
cD=average(LL && MM)/MMMM;
and MM has no coefficient of 2 , so
Is a coefficient of 0.5 for cD is missed?
Did anyone ever find out why the cD coefficient is missing the 0.5?
I've read the paper "A comparative study of subgrid scale models in homogeneous isotropic turbulence" by Fureby et al. and there the 0.5 is missing as well.
Could someone explain to me why that is the case?
