geo

module for including axisymmetric geometry in coordinates (z,r), with z the vertical coordinate and r the radial coordinate

struct containing the geometric data necessary for non-trivial axisymmetric geometries, to be passed around the inside of the code, replacing the geometry_input struct from input_structs.jl

The arrays of 2 dimensions are functions of (z,r)

function get_default_rhostar(reference_params)

Calculate $c_\mathrm{ref} / \Omega_\mathrm{ref} L_\mathrm{ref} = m_i c_\mathrm{ref} / e B_\mathrm{ref} L_\mathrm{ref}$.

This is similar to the de-dimensionalised ion gyroradius at reference parameters, which would be sqrt(2)*rhostar, as $v_{Ti}(T_\mathrm{ref}) = \sqrt{2 T_\mathrm{ref} / m_i} = \sqrt{2} c_\mathrm{ref}$.

function to initialise the geometry coefficients inputdata – geometryinput type z – coordinate type r – coordinate type

function to read the geometry input data from the TOML file

the TOML namelist should be structured like

[geometry] pitch = 1.0 rhostar = 1.0 DeltaB = 0.0 option = ""
