• Conditions for Earth-like geodynamo models (2010, background): “However, this goal, which has been called the ‘grand challenge’ by (Glatzmaier (2002), should be augmented by the requirement that the magnetic Reynolds number is in the range of possible Earth values.”
• Tidal heating in icy satellite oceans (2014, background): “Unfortunately, due to computational limitations, three-dimensional models that can include convection may not necessarily be more accurate than our shallow-water model, because these models are unable to resolve the processes that presumably dissipate energy in the system (Glatzmaier, 2002).”
• Characteristics-based marker-in-cell method with conservative finite-differences schemes for modeling geological flows with strongly variable transport properties (2003, background): “composition and also vector and tensor quantities, which would have direct applications in thermal-chemical convection (Hansen and Yuen, 2000), the geodynamo (Glatzmaier, 2002) and viscoelastic stress-transfer (Melini et al.”
• Dipole moment scaling for convection-driven planetary dynamos (2005, background): “In terms of the dimensionless parameters that control convective dynamos, this combination of factors means that the Rayleigh number is too small, and the Ekman and magnetic Prandtl numbers are too large in the dynamo models [18].”
• Estimates of heat flow in the deep mantle based on the power requirements for the geodynamo (2002, methodology): “Estimates from recent geodynamo models cannot be used directly because the values of the physical parameters and the approximations used in these calculations are not representative of the conditions in the core [Glatzmaier, 2002].”
• The influence of potassium on core and geodynamo evolution (2003, background): “Further numerical simulations of geodynamo activity (e.g. Kuang & Bloxham 1997; Glatzmaier 2002; Kutzner & Christensen 2002) may be helpful in resolving these questions.”
