| - | __Must Haves__ | ||
| - | |||
| - | - Boundary conditions: | ||
| - | - Temperature: Fixed temp or fixed flux at both boundaries | ||
| - | - Tangential Velocity: No slip or viscous stress-free or drag law | ||
| - | - Magnetic Field: Finitely conducting or insulating at both boundaries | ||
| - | - Radial velocity: impermeable or permeable | ||
| - | - Geometry: | ||
| - | - Prescription of inner core size, including no inner core | ||
| - | - Topography on boundaries (e.g. ellipticity, or mountains) | ||
| - | - External Influences: | ||
| - | - Mantle thermal heterogeneities as a thermal boundary condition | ||
| - | - External magnetic field sources | ||
| - | - Driving Mechanisms: | ||
| - | - Internal heating | ||
| - | - Compositional driving independent of thermal driving | ||
| - | - Precession, Tides, Mechanical torques (i.e. impacts, boundary motion) | ||
| - | - Stratification: | ||
| - | - Allowing radial stratification through background temperature profiles (i.e. fake heat sources in Boussinesq models) | ||
| - | - Internal interfaces | ||
| - | - Prescribed radial variations of internal heat sources, secular cooling, and compositional change (note: this is a generalization of item 5a). | ||
| - | - Temperature/pressure dependent physical parameters | ||
| - | - Different equations of state | ||
| - | - Radial variations (e.g. density, conductivity, viscosity…) | ||
| - | - Lateral variations (e.g. relating conductivity directly to temperature in Hot Jupiter atmospheres) | ||
| - | - allowing radiative regions in gas giant atmospheres | ||
| - | - Freely Rotating Inner core that can respond to torques from: | ||
| - | - Inner-core / Mantle gravitational coupling | ||
| - | - EM torques | ||
| - | - Viscous torques | ||
| - | - Pressure torques (with boundary topography) | ||
| - | - Implicit or explicit treatment of Coriolis force | ||
| - | |||
| - | __Dream of having__ | ||
| - | |||
| - | - As realistic parameter values as possible | ||
| - | - Subgrid-scale turbulence (perhaps this should go in the “must haves” based on Hiro’s & Bruce’s work?) | ||
| - | - Inner core physics | ||
| - | - convection in the inner core | ||
| - | - inner core translation | ||
| - | - phase equilibrium at inner core boundary | ||
| - | - inner core ellipticity – respond to gravitational torques in mantle | ||
| - | - Gravity field solver (including mantle density anomalies) | ||
| - | - Real geochemistry in the core | ||
| - | - snow zones | ||
| - | - helium rain | ||
| - | - other odd features due to chemistry in multi-component fluids | ||
| - | - mixtures of solids & fluids | ||
| - | - Mushy layer physics at ICB | ||
| - | - Solid/fluid mixtures | ||
