Description
Tremendous progress have been made in computing realistic global simulation of the solar magnetism and its 11 yr cycle. Yet there is still one paradox: none of the published dynamo simulations display sunspots. This is the so-called spotty-dynamo paradox. In this talk we will discuss what we think is missing in current global HPC simulation of the solar dynamo and 11 yr cycle and how new high resolution simulations can start developing field concentrations akin to sunspots helping disentangling various type of solar dynamo models such as Babcock-Leighton or alpha-omega.
