ElectromagneticFields.jl

Common Interface for Electromagnetic Fields

ElectromagneticFields.jl provides a common interface for evaluating analytical and numerical magnetic equilibria, general electromagnetic fields and in the future also simple Maxwell solvers. For analytical equilibria, it generates Julia code providing high-level evaluation routines. Numerical equilibria are interpolated using ApproXD and can be evaluated with the very same interface as the analytical equilibria.

Features

Analytical equilibria:

• simple axisymmetric tokamak equilibrium in cartesian, cylindrical and toroidal coordinates
• flexible Solov'ev equilibria with and without X-point
• simple quadratic Solov'ev equilibrium as well as symmetric quadratic field
• ABC field
• 3D perturbations (e.g., magnetic islands)

Numerical equilibria (planned):

• projected analytic equilibria
• EFIT
• VMEC

Numerical solvers (planned):

• B-Spline, FEM and pseudo-spectral Poisson, Ampère and Faraday solvers
