Numerical simulations of the geodynamo have successfully represented many observable
characteristics of the geomagnetic field, yielding insight into the fundamental processes that …

Solutal buoyancy has a large impact on the flow of the alloy phase composing the positive
electrode in liquid metal batteries. During discharge solutal buoyancy creates a stabilizing …

Convection in planetary cores can generate fluid flow and magnetic fields, and a number of
sophisticated codes exist to simulate the dynamic behaviour of such systems. We report on …

The mechanism by which the Earth's magnetic field is generated is thought to be thermal
convection in the metallic liquid iron core. Here we present results of a suite of self …

Numerical MHD simulations play an increasingly important role for understanding the
mechanisms of stellar magnetism. We present simulations of convection and dynamos in …

A striking feature of many natural dynamos is their ability to undergo polarity reversals,. The
best documented example is Earth's magnetic field, which has reversed hundreds of times …

We present a framework for the structure-preserving approximation of partial differential
equations on mapped multipatch domains, extending the classical theory of finite element …

Fluctuations in the length of day (LOD) over periods of several decades are commonly
attributed to exchanges of angular momentum between the mantle and the core. However …

Planets and stars are often capable of generating their own magnetic fields. This occurs
through dynamo processes occurring via turbulent convective stirring of their respective …

We present a fully spectral methodology for magnetohydrodynamic (MHD) calculations in a
whole sphere. The use of Jones–Worland polynomials for the radial expansion guarantees …
