The generation of energy-efficient parallel scientific codes became very important in the time of carbon footprint reduction. In this paper, we briefly present our latest particle-in-cell code with the results of a numerical simulation of plasma dyna

The problem of the evolution of an ion beam in a fully ionized plasma is investigated using computer simulation. The 2D-3V axisymmetric composite numerical model is based on the particle-in-cell (PIC) method for both the ion component of the backgrou

In the paper results for modelling a characteristic pattern of the solar wind flow and its turbulent structure are presented. We use a gravitational magnetic hydrodynamic model, and for the model we have created an effective numerical method based on

We present a new algorithm for numerical simulation of beam dynamics in the modern supercolliders, where the beams move with ultrarelativistic speeds and collide with crossing angle (~20 mrad). In case of critical charge densities the colliding beams

We present a three-dimensional (3-D) particle-in-cell (PIC) model and parallel code for the self-consistent motion of charged ultrarelativistic beams (${\it\gamma}\sim 10^{3}{-}10^{5}$) in supercolliders. We use the 3-D set of Maxwell’s equations f

We present a new finite-difference scheme for Maxwell's equations solution for three-dimensional domains with different scales in different directions. The stability condition of the standard leap-frog scheme requires decreasing of the time-step with
