Inductance

PyPI Status Python Version License Read the documentation at https://inductance.readthedocs.io/ Tests Codecov pre-commit Ruff

This is a python library to calculate inductance. Mostly for the purposes of calcualting magnetically confined plasmas. It might someday actually contain some plasma physics, but lets not get too carried away.

Features

  • Self-inductance formulas

    • self inductance of circular, circular hollow, and rectangular section by Maxwell's approximation
    • Lyle's approximation for thick coil solenoid self inductances to 4th and 6th order.
    • Butterworth's approximation for long solenoids
    • Lorentz's perfect analytic solution for current sheet solenoids
    • Babic and Akyel's approximation for thin solenoids

  • Mutual-inductance formulas

    • mutual inductance of filaments (Maxwell)

  • Filamentary models

    • utility functions to create filament arrays from rectangular definitions of coils and subcoils
    • calculation for filament array mutual inductance
    • calculation of filament array self inductance

  • Green's functions

    • calculation of Green's functions for Psi, Br, and Bz from filamented coils to points
      • with Numba, calculation of green's functions for arbitrary grids of points
    • calculation fo Green's functions for coil forces

  • Arbitrary coil shapes

    • rudimentary support for arbitrary wire filament coil shapes

Requirements

Inductance requires NumPy and uses Numba for acceleration. It is written in mostly pure python referencing academic articles for calculating inductances by various methods, most of which rely on elliptic functions. Inductance provides Numba accelerated pure python elliptic functions.

It is possible to remove the dependence on Numba and get most of the functionality of Inductance. The plan is to provide different options, including with alternative accelerators, such as JAX. For now, the requirements are:

  • python >= 3.8
  • numpy >= 1.24
  • numba >= 0.57

Installation

You can install inductance via pip from PyPI:

$ pip install inductance

Issues

For now, this is a very early release. It is likely a new top level API will be developed as the library matures.

If you encounter any problems, please file an issue along with a detailed description.
