  2. 21. Spectral Accuracy in Fast Ewald Methods and Topics in Fluid Interface Simulation

    Author : Dag Lindbo; Anna-Karin Tornberg; Michael S. Siegel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract :   This work contains two separate but related parts: one on spectrally  accurate and fast Ewald methods for electrostatics and viscous flow,  and one on micro- and complex fluid interface problems.  In Part I we are concerned with fast and spectrally accurate methods  to compute sums of slowly decaying potentials over periodic  lattices.
