Scaling properties of convection-driven dynamos in rotating spherical shells and application to planetary magnetic fields (2006, background): “Wicht (2002) found only small differences between the two options and we confirmed this in a few cases that have been run with both kinds of conditions.”
The Magnetic Field of Planet Earth (2010, background): “…enables the new polarity to establish itself in the entire core, and in particular within the inner core, as suggested by e.g. Gubbins (1999) following Hollerbach and Jones (1993, 1995) (though for an alternative view of the importance of magnetic diffusion in the inner core, see Wicht 2002).”
From solar-like to antisolar differential rotation in cool stars (2013, methodology): “Our numerical models are computed using the anelastic spectral code MagIC (Wicht 2002, GW12) that has been validated against hydrodynamical and dynamo benchmarks (Jones et al. 2011).”
Scaling regimes in spherical shell rotating convection (2016, methodology): “For the most demanding calculations, MagIC uses the open-source library SHTns‡ to speed-up the spherical harmonic transforms (Schaeffer 2013).”
Thermal and electrical conductivity of solid iron and iron-silicon mixtures at Earth's core conditions (2013, background): “ing no effect of conduction in the inner core (Wicht, 2002) and”
Modelling the palaeo-evolution of the geodynamo (2009, background): “(14) The other boundary conditions at both boundaries are of rigid type for velocity, and insulating for the magnetic field (the effect on inner-core conductivity on the long-term behaviour of dynamo simulations has been found to be negligible, as shown by Wicht 2002).”
The magnetic structure of convection-driven numerical dynamos (2008, background): “The outer boundary is electrically insulating, while the inner boundary can be either conducting (in model T, see Table 1) or insulating (in model C). The influence of a change in the latter boundary condition is generally thought to be insignificant for Earth’s core geometry ( Wicht 2002 ).”
Steady zonal flows in spherical shell dynamos (2005, methodology): “The numerical implementation MAGIC by Wicht (2002) is used.”
