Spectral Calculations of Isotropic Turbulence: Efficient Removal of Aliasing Interactions

An algorithm is given for the rapid calculation of the convolution sums appearing in the Fourier‐transformed Navier‐Stokes equations. In three space dimensions, the new algorithm is a factor of 4 more efficient than previously suggested algorithms.
