Module bout_interface 

BOUT++ coupling interface for 3D MHD stability analysis.

Generates field-aligned coordinate grids from 2D GS equilibria, computes metric tensors (g^ij, Jacobian, |B|), and exports in a text format compatible with BOUT++ input requirements.

Also provides import routines for BOUT++ stability results (growth rates, mode structure).

Structs

BoutGrid

BOUT++ field-aligned grid with metric tensors.

BoutGridConfig

Configuration for BOUT++ grid generation.

BoutStabilityResult

Parsed BOUT++ stability result (growth rate + mode structure).

Functions

export_bout_grid_text

Export BOUT++ grid to text format.

generate_bout_grid

Generate a BOUT++ field-aligned grid from a 2D equilibrium.

parse_bout_stability

Parse BOUT++ stability output (text format).
