init_quench_approx_if_needed#

exo_skryer.build_chem.init_quench_approx_if_needed(cfg: Any, exp_dir: Path) → None[source]#

Initialise the FastChem 5D grid and quench species list for quench_approx.

Reads fastchem_grid_jax (grid path, solver, species map) and quench_approx.quench_species from the YAML config. Both caches are idempotent — already-loaded caches are skipped.

Parameters:
cfgconfig object

Parsed YAML configuration object.

exp_dirPath

Experiment directory for resolving relative paths.
