The CHEASE code for toroidal MHD equilibria
收藏资源简介：
Abstract The CHEASE code (Cubic Hermite Element Axisymmetric Static Equilibrium) solves the Grad-Shafranov equation for toroidal MHD equilibria using a Hermite bicubic finite element discretization with pressure, current profiles and plasma boundaries specified by analytical forms or sets of experimental data points. Moreover, CHEASE allows the automatic generation of pressure profiles marginally stable to ballooning modes or with a prescribed fraction of bootstrap current. The code provides equilibri... Title of program: CHEASE Catalogue Id: ADDH_v1_0 Nature of problem CHEASE [1] solves the Grad-Shafranov equation [2, 3, 4] for the MHD equilibrium of a Tokamak-like plasma with pressure and current profiles specified by analytic forms or sets of data points. Equilibria marginally stable to ballooning modes [5] or with a prescribed fraction of bootstrap current [6, 7, 8] can be computed. The code provides a mapping to magnetic flux coordinates, suitable for MHD stability calculations or global wave propagation studies. The code computes equilibrium quantities fo ...
