utils.GhiaValidator#

class utils.GhiaValidator(h5_path: Path | str, Re: float | None = None, validation_data_dir: Path | str | None = None)[source]#

Validator for lid-driven cavity results against Ghia et al. (1982) benchmark.

Parameters:

Refloat: Reynolds number of the simulation (can also be inferred from HDF5 file).
h5_pathPath or str: Path to HDF5 file with solution fields.
validation_data_dirPath or str, optional: Directory containing Ghia CSV files. If None, uses default location.

Methods

`__init__`	Initialize validator and load solution fields from HDF5 file.
`compute_errors`	Compute error metrics against Ghia benchmark data.
`plot_validation`	Plot velocity validation against Ghia benchmark using seaborn.
`print_summary`	Print validation summary with error metrics.

Attributes

Examples using `utils.GhiaValidator`#

compute_errors()[source]#

Compute error metrics against Ghia benchmark data.

Returns:

dict: Dictionary containing error metrics for u and v velocities: - ‘u_l2’: L2 norm of u error - ‘u_linf’: L∞ (maximum) norm of u error - ‘u_rms’: Root mean square error for u - ‘v_l2’: L2 norm of v error - ‘v_linf’: L∞ (maximum) norm of v error - ‘v_rms’: Root mean square error for v

plot_validation(output_path: Path | str | None = None, show: bool = False)[source]#

Plot velocity validation against Ghia benchmark using seaborn.

Creates a two-panel figure with u and v velocity validation side-by-side.

Parameters:

output_pathPath or str, optional: Path to save figure. If None, figure is not saved.
showbool, default False: Whether to show the plot.
