Also, Guo et al. performed the whole domain decomposition by using the Peano-Hilbert curve in their ISPH code. In SPH, particles change positions due to the Lagrangian nature of the method.

WebThe fundamental Hilbert shape (a line joining the four corners of a square) is represented by two variables with values of either 0 or 1. This coding technique could be successfully applied to the generation of other regular space-filling curves, such as the Peano curve. http://people.stern.nyu.edu/kbauman/research/papers/2006_TheDilationFactorOfThePeanoHilberCurve.pdf

The Hilbert curve (also known as the Hilbert space-filling curve) is a continuous fractal space-filling curve first described by the German mathematician David Hilbert in 1891, as a variant of the space-filling Peano curves discovered by Giuseppe Peano in 1890. Because it is space-filling, its Hausdorff … See more Both the true Hilbert curve and its discrete approximations are useful because they give a mapping between 1D and 2D space that preserves locality fairly well.
