Numerical solution to the Vlasov equation: the 2D code

The present code solves the two-dimensional Vlasov equation for a periodic in space system, in presence of an external magnetic field B-o. The self co herent 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 projec tions of the distribution function in different subspaces as the x-u(x) spa ce, the x-y space and so on, (C) 1999 Elsevier Science B.V.
