Abstract

In this paper, we mainly discuss the reconstruction of 3D coronal magnetic fields from observed boundary magnetogram data under the general (non-constant-α) force-free assumption for flare events. These methods can perhaps be divided into 4 classes according to their mathematical bases for practical implementations: direct numerical discretization of the force-free field equations by the finite difference method (FDM); numerical treatment of the variational problem of the force-free field, or the finite element method (FEM); numerical treatment of the boundary integral equation of the force-free field, or the boundary element method (BEM); and the quasi-physical evolution from MHD equations to the force-free state. We will, however, present the results mostly obtained by the BEM and compare the reconstructed 3D coronal magnetic structures with Hα, soft X-ray, UV/EUV images and/or radio observations so as to understand the triggering and energy release processes in these flare events.
