Query: Discrete Filters for Large Eddy Simulation of Forced Compressible MHD
  Turbulence   In present study, we discuss results of applicability of discrete filters for
large eddy simulation (LES) method of forced compressible magnetohydrodynamic
(MHD) turbulent flows with the scale-similarity model. Influences and effects
of discrete filter shapes on the scale-similarity model are examined in
physical space using a finite-difference numerical schemes. We restrict
ourselves to the Gaussian filter and the top-hat filter. Representations of
this subgrid-scale model which correspond to various 3- and 5-point
approximations of both Gaussian and top-hat filters for different values of
parameter $\epsilon$ (the ratio of the mesh size to the cut-off lengthscale of
the filter) are investigated. Discrete filters produce more discrepancies for
magnetic field. It is shown that the Gaussian filter is more sensitive to the
parameter $\epsilon$ than the top-hat filter in compressible forced MHD
turbulence. The 3-point filters at $\epsilon=2$ and $\epsilon=3$ give the least
accurate results and the 5-point Gaussian filter shows the best results at
$\epsilon=2$.
