| 英文摘要 | A direct boundary integral formulation for a force-free magnetic field with finite energy content in the semispace above the Sun is presented. This is a new formulation for a three-dimensional nonlinear force-free field in which the boundary data can easily be incorporated. We have proposed an optimal method to numerically find the non-constant-alpha force-free field solution at any position in semispace. Therefore, the present computational procedure for the new representation is actually a pointwise method, so that no volume integration is needed. A test case study has been carried out to demonstrate the convergence, accuracy, and efficiency of the numerical procedures. The computational procedure is quite robust. The agreement between numerical and exact results validates the correctness and merits of the new formulation and computational procedure proposed. The application of the new direct boundary integral formulation to practical solar magnetic field problems is straightforward and prospective. |
