Supercomputer simulation of plasma electron dynamics in a magnetic trap with inverse magnetic mirrors and multipole magnetic walls

The problem of simulation of plasma electron dynamics in the magnetic trap with inverse magnetic mirrors and multipole magnetic walls is considered. The model is built on the basis of Particle-In-Cell method. The complexity of processes under study and the necessary in a high precision of results required the development...

Two-level explicit difference schemes

The main disadvantage of explicit schemes for the numerical solution to nonstationary problems is in a very strong stability condition for the size of a time step size. One of the possibilities to improve the efficiency of explicit algorithms is to use different time steps in different space subdomains. From...

Studying a spatial-temporal distribution of seismicity in the area around Fukushima Prefecture by GIS-EEDB program tools

In this paper, a modification of the high-tech expert system GIS-EEDB (Expert Earthquakes Database) intended for solving a wide range of seismological research tasks, called "Fukushima-EEDB" is proposed. For the first time the system was developed on the platform of Windows 8. The basic logical and functional structure as well...

The advantage of the GPU-based supercomputer simulation of plasma phenomena

A 3D kinetic study of the plasma relaxation processes caused by the propagation of an electron beam in high-temperature plasma was carried out. The mathematical model is built on the basis of the Particle-in-Cell (PIC) method. The performance for supercomputers powered by both Intel Xeon processors and Nvidia Tesla GPUs...
