Advanced geodynamo simulations at high resolution are obtained from previous approximated low-resolution cases. This ‘upsizing’ procedure does not perturb the leading-order dynamical characteristics of the previously obtained solutions, and enables an exploration of the properties of magnetohydrodynamic turbulence in the geodynamo.
