We describe the construction of stepped-pressure equilibria as extrema of a
multi-region, relaxed magnetohydrodynamic (MHD) energy functional that combines
elements of ideal MHD and Taylor relaxation, and which we call MRXMHD.
The model is compatible with Hamiltonian chaos theory and allows the
three-dimensional MHD equilibrium problem to be formulated in a well-posed
manner suitable for computation.
The energy-functional is discretized using a mixed finite-element,...[Show more]
