A purely internally heated planetary mantle with strongly temperature dependant viscosity is forming a so-called degree-one convection, a possible origin of the dichotomy of mars.
You see a volume rendering with streamlines in a sliced spherical shell (cold is more transparent than hot).
Details:
- Inner/outer radius ratio: 0.55
- Surface Rayleigh: 10000
- Gamma: 90
- Bottom insulated
- Free slip (surface and bottom)
- Cold random start
- Calculated on 128 CPUs at the supercomputing center in Juelich
Beautiful!!
