This work is devoted to developing algorithms for the solution of wave problems in mathematical physics on the basis of the boundary element method (BEM). The main advantages of the boundary element method is reduced to one dimension of the problem and transfer sample to the boundary of the study area, as well as obtaining a continuous solution in the region. As a consequence, reduces the amount of calculation and improves the accuracy of the...
We describe the large-scale model geodynamo, which based on indirect data of inhomogeneities in the density of the Earth’s core. Convection structure is associated with spherical harmonic Y42, which defines the basic poloidal component of velocity. Coriolis drift of this mode determines the toroidal component of velocity. Thus, 6 convective cells are formed. The model takes into account the feedback effect of the magnetic field on convection.It was ascertained that the model contains stable regimes...
