Simulation data provenance: GHOST code
See README-rotstrat4096 for more details✪ Direct numerical simulation (DNS) of rotating and stratified turbulence using 4,0963 nodes, on a periodic grid using a pseudo-spectral parallel code, GHOST.
✪ Navier-Stokes/Boussinesq equations are solved using a pseudo-spectral method.
✪ Solid body rotation force acting as the only external forcing mechanism.
✪ Time integration uses fourth-order Runge-Kutta.
✪ After the simulation has reached a statistical stationary state, 5 frames of data, which includes the 3 components of the velocity vector and the temperature fluctuations, are generated and written in files that can be accessed directly by the database (FileDB system).
