Efficiency and Accuracy Improvements for FastStokes, A Precorrected-FFT Accelerated 3-D Stokes Solver

Keywords: , ,

In this paper we present several efficiency and accuracy improvement to the precorrected-FFT accelerated Stokes flow solver, FastStokes. Accuracy was improved by deriving analytical formulas for required integrals of Stokes equation Green sfunctions, cpu time was reduced by nearly a factor of three by replacing nine scalar convolutions with a more efficient ‘vector’ convolution, and both memory and cpu time were reduced by replacing a collocation-based projection scheme with a transposed polynomial interpolation scheme.
