Please find my talk below to be given at University of Southampton for the STFC Advanced Summer School:
My talk will be on my recent work aiming to reproduce and extend the results of Stellmach & Hansen (2004) where they numerically simulate Cartesian convection-driven dynamos at low Ekman numbers and produce a subcritical dynamo. That is, dynamo action below the convective onset. I have recently managed to reproduce this subcritical dynamo and now aim to extend the study to lower Ekman numbers and further into the subcritical regime.
