Abstract: A hybrid spectral/finite-element code, NTEC, is developed to numerically solve the resistive finite-pressure magnetohydrodynamic equilibria in non-axisymmetric toroidal systems. The adopted approach integrates a hyperbolic parallel damping equation for pressure updating, along with a dynamic resistive relaxation for the magnetic field. To address the nonaxisymmetry in toroidal geometry, a pseudo flux mapping is employed to relate the axisymmetric computational domain to the physical domain. On the computational mesh, an isoparametric C1-continuous triangular element is utilized to discretize the poloidal plane, which is complemented with a Fourier decomposition in the toroidal direction. For the calculation results, we first benchmark the NTEC solutions with a fixed-plasma-boundary classic stellarator equilibrium from SIESTA and the free-plasma-boundary CFQS equilibria from HINT. We then show the NTEC results in the standard CFQS equilibria, the TCV-like tokamak helical-core equilibria, and the KTX-like RFP quasi-single-helicity equilibria.
