Grid

class sunkit_magex.pfss.grid.Grid(ns, nphi, nr, rss)

Bases: object

Grid on which the sunkit_magex.pfss solution is calculated.

Notes

The PFSS solution is calculated on a “strumfric” grid defined by

• \(\rho = \log (r)\)

• \(s = \cos (\theta )\)

• \(\phi\)

where \(r, \theta, \phi\) are spherical coordinates that have ranges

• \(1 < r < r_{ss}\)

• \(0 < \theta < \pi\)

• \(0 < \phi < 2\pi\)
