چکیده
The extended boundary node method (X-BNM) has been applied to a boundary-value problem of the Grad-Shafranov (G-S) equation and its performance has been numerically investigated by comparing with the dual reciprocity boundary element method (DRM). The result of computations shows that the accuracy of the X-BNM is higher than that of the DRM. Therefore, it is found that the X-BNM might be a powerful tool for solving a boundary-value problem of the G-S equation.

Numerical Approach Based on Extended Boundary Node Method for Solving Grad-Shafranov Equation
The boundary element method (BEM) is one of numerical methods for the boundary-value problem of partial differential equations and has been so far used in the fields of plasma and fusion science. For example, the BEM has been adopted for solving the Grad-Shafranov (G-S) equation which describes the magnetohydrodynamics equilibrium in an axisymmetric plasma [1]. On the other hand, Mukherjee et a...
متن کاملTheory of perturbed equilibria for solving the Grad-Shafranov equation
The theory of perturbed magnetohydrodynamic equilibria is presented for di erent formulations of the tokamak equilibrium problem. For numerical codes, it gives an explicit Newton scheme for solving the Grad-Shafranov equation subject to di erent constraints. The problem of stability of axisymmetric modes is shown to be a particular case of the equilibrium perturbation theory.
