FPPAC88 - A TWO-DIMENSIONAL MULTISPECIES NONLINEAR FOKKER-PLANCK PACKAGE

FPPAC88 solves the complete nonlinear multispecies Fokker-Planck collision operator for a plasma in two-dimensional velocity space. This program is a NEW VERSION of FPPAC, which was published in Computer Physics Communications in 1981. The most important new feature is the modification of the spatial differencing to accommodate situations in which advection dominates diffusion. Another important change is the discontinuance of the CDC-7600 version of FPPAC; thus the NEW VERSION, FPPAC88, is applicable to machines with a single fast memory, in particular the Cray-1 with the CFT compiler. Any departures from standard FORTRAN are easily accommodated, so that FPPAC88 may be run on almost any supercomputer with a FORTRAN-77 compiler.
