# A Fokker-Planck code for the numerical solution of the plasma heating and the current drive problems with synergetic effects

## Description

Abstract A code developed to solve the quasilinear 2-D Fokker-Planck equation and previously applied to study the synergetic effect of lower hybrid current drive (LHCD) with electron cyclotron (EC) heating [Comput. Phys. Commun. 55 (1989) 253] is generalized to solve the current drive problem involving the synergetic effect of fast waves with electron cyclotron waves or of fast waves (FW) with lower hybrid waves. The code is relativistic and is no longer than about 170 FORTRAN lines. The input data fo... Title of program: SOLV2DFP Catalogue Id: ACPK_v1_0 Nature of problem A code is presented that solves numerically the linearized relativistic 2-D Fokker-Planck equation for the problem of plasma heating or current drive using lower hybrid waves, fast waves, electron cyclotron waves, as well as the synergetic effects of these waves. The code uses the IMSL finite element library PDE-PROTRAN, or its new version PDE2D. Very good precision for the solution of the distribution function can be obtained for high relativistic velocities, which allows the hot population to ...
