Description

Abstract The present code solves the two-dimensional Vlasov equation for a periodic in space system, in presence of an external magnetic field B_0 . The self coherent electric field given by Poisson equation is computed by Fast Fourier Transform (FFT). The output of the code consist of a list of diagnostics, such as total mass conservation, total momentum and energies, and of projections of the distribution function in different subspaces as the x-v_xspace, the x-y space and so on. Title of program: vl2dper Catalogue Id: ADJR_v1_0 Nature of problem Since the seventies, two main types of code are available to simulate plasma evolution: Particles (Lagrangian) codes or Eulerian codes. The advantage of particles codes is their capacity to go to high dimensions (two or three), their inconvenience the difficulty they have to represent with a good accuracy high velocity particles, and the numerical noise of the code, due to the too low number of particles used. Hybrid methods such as the deltaF method [2] or VHS method [3] mixing particles and ph ...
