Abstract. In this paper we present two equilibrium solvers for axisymmetrical
toroidal configurations, both based on the expansion in poloidal angle
method. The first one has been conceived as a two-point boundary value solver
in a system of coordinates with straight field lines, while the second one
uses a well-conditioned Cauchy formulation of the problem in a general
curvilinear coordinate system. In order to check the capability of our moment
methods to describe equilibrium accurately, a comparison of the moment
solutions with analytical solutions obtained for a Solov'ev equilibrium has
been performed.
