Optimal choice of grid points in multidimensional pseudospectral Fourier methods
The authors show that for multidimensional pseudospectral Fourier methods sampling efficiency is improved by using a skewed grid derived from a dense packing of spheres rather than a rectangular grid. A considerable gain is found for the five-dimensional Laplacian and for a pair of hydrogen atoms.
