3D magnetohydrodynamic equilibria with anisotropic pressure
An energy functional is proposed as a variational principle to determine three-dimensional magnetohydrodynamic (MHD) equilibria with anisotropic plasma pressure. Numerical procedures already developed for the scalar pressure model can easily be extended to the anisotropic pressure model within the formulation that has been adopted to treat this problem. Specifically, a steepest descent procedure, coupled with the application of a preconditioning algorithm to improve the convergence behaviour, has been employed to minimise the energy of the system. The numerical generation of 3D torsatron equilibria with highly localised anisotropic pressure distributions attests to the robustness of the method of solution considered.
