Abstract


In Tokamak wave heating the physical phenomena are important aspects of the study . The numerical simulation is an important means to study the wave heating . The TORIC code full wave solutions for numerical simulation of ion cyclotron wave heating only the history of the last two years , the procedural aspects of the main M.Brambilla represented by and represented by EFJaeger AORSA code. These full-wave solution code for the electromagnetic field algorithm , there are still some issues to be resolved . Modern computational electromagnetics finite-difference time-domain (FDTD) algorithm is considered most likely to solve those problems . With the emergence of parallel technology to solve the problems computationally intensive electromagnetic calculations . This paper describes a numerical algorithm for full-wave solution . This paper mainly introduce the numerical solution of linear equations , and nonlinear instabilities such as stimulated Raman scattering ( SBS ) . Linear model , compare the difference between the dispersion stability of the explicit FDTD differential and semi- implicit difference method . Nonlinear model , using the explicit FDTD method and the MacCormack scheme for numerical computation , the preliminary results of nonlinear . These methods are used to parallel computing methods , and a preliminary inquiry in the parallel case of boundary conditions .
