CLI

The command-line interface is exposed through flow-props.

Overview

1	`flow-props --help`

Available subcommands:

Extract wall-normal profiles at selected stations:

flow-props profiles \
  --input solution.vtu \
  --stations 10,50,100 \
  --j-max 80 \
  --output profiles.json

Compute \(\delta\), \(\delta^*\), \(\theta\), and \(H\):

flow-props bl \
  --input solution.vtu \
  --stations 10,50,100 \
  --criterion velocity_ratio \
  --threshold 0.99 \
  --output bl.json

For an enthalpy-based edge criterion:

flow-props bl \
  --input solution.vtu \
  --stations 10,50,100 \
  --criterion enthalpy_ratio \
  --threshold 0.99

For a derivative-based criterion:

flow-props bl \
  --input solution.vtu \
  --stations 10,50,100 \
  --criterion velocity_gradient \
  --gradient-threshold 0.0

flow-props entropy \
  --input solution.vtu \
  --stations 10,50,100 \
  --threshold 0.25 \
  --output entropy.json

flow-props wall \
  --input solution.vtu \
  --mu-wall 1.8e-5 \
  --output wall.json

Add freestream and thermal inputs if you want \(C_f\), \(q_w\), and \(St\):

flow-props wall \
  --input solution.vtu \
  --mu-wall 1.8e-5 \
  --output wall.json

Each command can print a starter TOML block:

flow-props bl --init
flow-props entropy --init
flow-props wall --init
flow-props profiles --init
