More efficient time integration for Fourier pseudo-spectral DNS of incompressible turbulence
David I. Ketcheson, Mikael Mortensen, Matteo Parsani +1
Time integration of Fourier pseudo-spectral DNS is usually performed using the classical fourth-order accurate Runge--Kutta method, or other methods of second or third order, with…
Fast parallel multidimensional FFT using advanced MPI
Lisandro Dalcin, Mikael Mortensen, David E Keyes
We present a new method for performing global redistributions of multidimensional arrays essential to parallel fast Fourier (or similar) transforms. Traditional methods use standar…
Slope limiting the velocity field in a discontinuous Galerkin divergence free two-phase flow solver
Tormod Landet, Kent-Andre Mardal, Mikael Mortensen
Solving the Navier-Stokes equations when the density field contains a large sharp discontinuity---such as a water/air free surface---is numerically challenging. Convective instabil…
