## A 3D numerical model for the Earth’s mantle convection

By now a substantial body of literature has evolved which deals with the numerical simulation of the 3D convective currents in the Earth’s mantle (see, e.g., [1–4] and references therein). A crucial point is to estimate the reliability of numerical experimental results because the similarity principle fails when the dynamical...

## Analysis of solitons in protoplanetary disc with MVS-1000M

With MVS-1000M the distribution of particle and gas density in the soliton were investigated, as well as their velocities, angular momentum, flow of gas and particles through soliton and vorticity of particle velocity. It is shown that in the soliton the high values of gas and dust densities and gas...
