Accurate computations of turbulent flows using the Large-Eddy Simulation (LES) technique with an appropriate SubFilter Scale (SFS) model require low artificial dissipation such that the physical energy cascade process is not perturbed by numerical artifacts. To realize this in practical simulations. energy-conserving numerical schemes and high-quality computational grids are needed. I... https://www.tftoyes.shop/product-category/dungeons-and-dragons/
