Abstract: Abstract Recent results are presented for convection driven dynamos in rotating spherical fluids shells which are obtained from computations carried out at the Stuttgart Supercomputing Center. Studies of the dependence on the Prandtl number P indicate that dynamo action disappears with increasing P unless the magnetic Prandtl number P m is also increased. Relaxation oscillations of convection coupled to magnetic torsional oscillations are found at low Prandtl numbers and various types of reversals of dipolar dynamos have been identified.
