Marklin: A 3D force-free equilibrium solver

Table of Contents

• Marklin Examples

Marklin solves variants of the uniform current \( \lambda = const \) force-free ideal MHD equilibrium equation

\[ \mu_0 \textbf{J} = \nabla \times \textbf{B} = \lambda \textbf{B}. \]

Marklin Examples

The following examples illustrate usage of Marklin to compute compute different 3D force-free equilibria (Taylor states).

Python interface

• Marklin Example: Compute and trace Taylor states in an elongated cylinder
• Marklin Example: Compute vacuum field in a 3D boundary (NCSX)

Fortran interface

• Marklin Example: Force-free eigenmodes
• Marklin Example: Inhomogeneous Ideal MHD Equilibria
