Profiles

Module: flow_props.profiles

Purpose

This module extracts wall-normal slices from a structured CFD dataset.

Main Function

extract_profiles(ds, stations, j_max=None)

Returns a list of profile dictionaries, one per station.

Each profile contains:

• x
• y
• eta
• one array per flow variable in the dataset

Notes

• the dataset must use a StructuredGrid
• eta is built from cumulative arc length along the wall-normal line
• j_max can truncate the wall-normal extent for focused near-wall analysis
