Kinetic particle-in-cell codes are vastly applied to modeling small-scale plasma processes in space and laboratory plasmas.
I will review recent results of three-dimensional kinetic modeling of magnetic reconnection with implicit kinetic PIC code iPic3D.
Particular emphasis will be given to the peculiarities in magnetic field topology (magnetic nulls) and their relation to energy dissipation events.
An important finding is that magnetic nulls of particular, spiral topological type, manifest energy dissipation sites far from the main reconnection X-line.
Computational particles are also used magnetohydrodynamic modeling of fluids and plasmas.
A new Lagrangian magnetohydrodynamic Particle-in-Cell solver, Slurm, is being developed at KU Leuven.
Slurm is the first ever particle-based MHD code specially designed to study CME and shock propagation in the heliosphere.
Extensive testing on classical two-dimensional problems have proven feasibility of the new approach and efficiency of the new algorithm.
The code has been enhanced with various types of initial and boundary conditions necessary for studying CME propagation.
I will describe the new algorithm, the structure of the code, and the first results of testing. |
