I work at "FRACTAL GRIDS". I have found this hypothesis "The blockage ratio σ is the same for both grids, σ ≈ 32%. It is also of interest to define the thickness ratio of each grid: tr = tmax/tmin = 8.5 for the fractal square grid and tr = 1 for the regular one. Numerically, we set tmin = 1 " in many articles. Can I know why?


FRACTAL GRIDS :




tmin ->Minimum thickness
