Simulation of an electron beam and plasma interaction

The problem of an electron beam and plasma interaction, arising from the GOL-3 (BINP SB RAS) experiments, is considered. For the given problem, it is appropriate to use the collisionless plasma approach, described by a set of the Vlasov–Maxwell equations. The Vlasov equation is calculated via the particle-in-cell method. To...

Automation of initial data input in the program package ERA-DD for solving two-dimensional boundary value problems on quasi-structured grids

A graphical user interface of the program package ERA-DD for the input and editing of initial data for a two-dimensional boundary value problem is described. The boundary of calculation domain is approximated by pieces of straight lines and circle arches. The input of the information about the boundary is provided...

Particle-in-Cell method with adaptive mass

In this paper, the PIC method with an adaptive mass is introduced. This enables us to conserve the velocity distribution, and not only density, momentum, the center of mass, energy in a cell. This is important for simulating multi-stream flows. That is why this modification was tested on the Riemann...
