load_nasa9_if_needed#

exo_skryer.build_chem.load_nasa9_if_needed(cfg: Any, exp_dir: Path) → None[source]#

Load NASA-9 thermo coefficients if RateJAX chemistry requires it.

This function checks if the configured chemistry scheme requires Gibbs free energy data (RateJAX chemical equilibrium modes) and loads the NASA-9 tables if needed. If data is already loaded or not required, it returns immediately.

Parameters:
cfgconfig object

Parsed YAML configuration object with cfg.physics.vert_chem attribute.

exp_dirPath

Experiment directory used to resolve relative paths to NASA-9 data.
