Semiconvection: numerical simulations [PDF]
Astronomy & Astrophysics, 2013 A grid of numerical simulations of double-diffusive convection is presented for the astrophysical case where viscosity (Prandtl number Pr) and solute diffusivity (Lewis number Le) are much smaller than the thermal diffusivity.

Numerical simulations of sunspots [PDF]
Proceedings of the International Astronomical Union, 2007 The origin, structure and evolution of sunspots are investigated using a numerical model. The compressible MHD equations are solved with physical parameter values that approximate the top layer of the solar convection zone.

Numerical simulations of jets [PDF]
New Astronomy Reviews, 2021 When astrophysical jets were discovered one hundred years ago, the field of numerical simulations did not yet exit. Since the arrival of programmable computers though, numerical simulations have increasingly become an indispensable tool for dealing with “tough nut” problems which involve complex dynamic and non-linear phenomena.

Numerical simulation of a guitar [PDF]
Computers & Structures, 2003 The purpose of this study is to present a time-domain numerical modeling of the guitar. The model involves the transverse displacement of the string excited by a force pulse, the flexural motion of the soundboard and the sound radiation in the air. We use a specific spectral method for solving the Kirchhoff-Love's dynamic plate model for orthotropic ...

Numerical Simulation of Mammatus [PDF]
Journal of the Atmospheric Sciences, 2008 AbstractMammatus are hanging lobes on the underside of clouds. Although many different mechanisms have been proposed for their formation, none have been rigorously tested. In this study, three-dimensional numerical simulations of mammatus on a portion of a cumulonimbus cirruslike anvil are performed to explore some of the dynamic and microphysical ...

Efficient numerical simulations with Tensor Networks: Tensor Network Python (TeNPy) [PDF]
SciPost Physics Lecture Notes, 2018 Tensor product state (TPS) based methods are powerful tools to efficiently simulate quantum many-body systems in and out of equilibrium. In particular, the one-dimensional matrix-product (MPS) formalism is by now an established tool in condensed matter ...
