A model of thermally driven dynamo in the Boussinesq approximation in the spherical shell with the free rotating inner core is considered. To solve equations we use new in dynamo modeling control volume technique. The main advantage of this method of solving magnetohydrodynamics equations in the spherical grids is that no filtering of high harmonics in the pole regions is needed.
