Journal ArticleDOI
Simulations of nonhelical hydromagnetic turbulence.
TL;DR: The bottleneck effect is shown to be equally strong both for magnetic and nonmagnetic turbulence, but it is far weaker in one-dimensional spectra that are normally studied in laboratory turbulence.
Journal ArticleDOI
Hydromagnetic turbulence in computer simulations
TL;DR: The usefulness of high-order schemes in astrophysical MHD turbulence simulations is discussed in this paper, where simple advection tests of hat profiles are used to compare schemes of different order.
Journal ArticleDOI
Is Nonhelical Hydromagnetic Turbulence Peaked at Small Scales
TL;DR: In this paper, the authors considered nonhelical hydromagnetic turbulence without an imposed magnetic field and showed that the magnetic energy spectrum peaks at a wavenumber of about 5 times the minimum waveform in the domain and not at the resistive scale, as has previously been argued.
Journal ArticleDOI
Bottleneck effect in three-dimensional turbulence simulations.
TL;DR: At numerical resolutions around 512(3) and above, three-dimensional energy spectra from turbulence simulations begin to show noticeably shallower spectra than k-5/3 near the dissipation wave number ("bottleneck effect").

TL;DR: The Pencil Code is a highly modular physics-oriented simulation code that can be adapted to a wide range of applications, primarily designed to solve partial differential equations of compressible hydrodynamics but can also evolve Lagrangian particles, their coagulation and condensation, as well as their interaction with the fluid.
