FPPAC94: A two-dimensional multispecies nonlinear Fokker-Planck package for UNIX systems
Description
Abstract FPPAC94 solves the complete nonlinear multispecies Fokker-Planck collison operator for a plasma in two-dimensional velocity space. The operator is expressed in terms of spherical coordinates (speed and pitch angle) under the assumption of azimuthal symmetry. Provision is made for additional physics contributions (e.g. rf heating, electric field acceleration). The charged species, referred to as general species, are assumed to be in the presence of an arbitrary number of fixed Maxwellian speci... Title of program: FPPAC94 Catalogue Id: AAQU_v4_0 [ACTM] Nature of problem The complete nonlinear multispecies Fokker-Planck collision operator for a plasma in two-dimensional velocity space is solved. The operator is expressed in terms of spherical coordinates (v = speed, theta = angle between velocity and magnetic field directions, phi = azimuthal angle) under the assumption of azimuthal symmetry. Provision is made for additional physics contributions.
