High Rayleigh number simulations in a cylinderical cell with aspect-ratio 1/3

The results of DNS simulations of Rayleigh-B\'enard convection with Ra up to $10^{12}$ in a cylindrical geometry with aspect-ratio 1/3 are presented. The simulations were carried out on a PRACE tier 0 grant illustrating the size of the computational task, which required millions of CPU hours. With Pr $= 0.7$ these simulations match the new experimental setup build in the ``U-boat of G\"ottingen.'' We show global quantities such as the heat transport as well as local time-averages. The boundary layer profile and the strength of the large scale circulation are studied and movies of horizontal cross-section of the bulk and the boundary layer are shown.
