Hello Ramiro,

You can use the UnitConverterFromResolutionAndLatticeVelocity with lattice velocity between 0,1 and 0,15. That will give you the highest possible relaxation time in the chosen resolution. Then look at SmagorinskyBoussinesqCouplingPostProcessor3D. You can stabilize your simulation there with the turbulent Prandtl number.
