Proceedings of the US-Japan Workshop on Advanced Plasma Modeling II Held in Nagoya, Japan on March 23-27, 1987
Abstract
The numerical properties of a gyrokinetic plasma have been discussed in detail in this workshop. It is generally agreed that considerable improvement in time step, grid spacing and noise level can indeed be realized with the present model. Numerical schemes for solving the nonlinear gyrokinetic equations have also been presented. The consensus is that the treatment of the electron motion parallel to the magnetic field is very crucial. The proposed sub-cycling scheme should be examined carefully. With the arrival of the present generation of super computers, the time has come to work actively toward the realistic simulation of tokamak discharges with particle codes - gyrokinetic or implicit. However, there are numerous important issues one has to resolve before achieving that goal, such as particle re-cycling techniques, 3D diagnostics, the Magnetohydrodynamic equilibrium problem, the development of collision operators and the choice of the appropriate coordinate systems for the simulation. Another important aspect is the inclusion of the kitchen physics in the code. Keywords: Computerized simulation; Solar wind; Alfuen waves; Symposia; Japan.
