Resumo
The dynamo mechanism, responsible for the solar magnetic activity, is still an open
problem in astrophysics. Different theories proposed to explain such phenomena have failed in
reproducing the observational properties of the solar magnetism. Thus, ab-initio computational
modeling of the convective dynamo in a spherical shell turns out as the best alternative to tackle
this problem. In this work we review the efforts performed in global simulations over the past
decades. Regarding the development and sustain of mean-flows, as well as mean magnetic field,
we discuss the points of agreement and divergence between the different modeling strategies.
Special attention is given to the implicit large-eddy simulations performed with the EULAG-MHD code.
