The magnetic fields of the planets, including the Earth, are generated by dynamo action in
their fluid cores. Numerical models of this process have been developed that solve the …

In 1995, two groups [Kageyama et al., 1995; Glatzmaier and Roberts, 1995a, 1995b]
reported results of numerical integrations of fully three‐dimensional, fully nonlinear …

We present an attempt to reach realistic turbulent regime in direct numerical simulations of
the geodynamo. We rely on a sequence of three convection-driven simulations in a rapidly …

In this paper, we report on very efficient algorithms for spherical harmonic transform (SHT).
Explicitly vectorized variations of the algorithm based on the Gauss‐Legendre quadrature …

Self-sustained convective dynamos in planetary systems operate in an asymptotic regime of
rapid rotation, where a balance is thought to hold between the Coriolis, pressure, buoyancy …

A new kind of overset grid, named Yin‐Yang grid, for spherical geometry is proposed. The
Yin‐Yang grid is composed of two identical component grids that are combined in a …

The past several years have seen dramatic developments in the study of planetary magnetic
fields, including a wealth of new data, mainly from the Galilean satellites and Mars, together …

Speculation about its possible super-rotation has drawn the attention of many geophysical
researchers to the Earth's inner core. An issue of special interest for geodynamo modelling …

Magnetism is one of the most pervasive features of the Universe, with planets, stars and
entire galaxies all having associated magnetic fields. All of these fields are generated by the …
