Usage

CLI Usage

The pxios CLI tool can be used to list and fetch available models:

pxios list                 # list all models present
pxios fetch model.ext      # fetch a specific model
pxios fetch ext            # fetch all models of an extension

Fetch via Python

from polyxios.fetcher import fetch, fetch_by_extension

# Fetch a single file - downloads the format archive on first use
path = fetch("cube86.mesh")         # medit format
path = fetch("pyra_cube.ugrid")     # ugrid format
path = fetch("20mm-xyz-cube.stl")   # stl format

# Fetch all files of a format
paths = fetch_by_extension(".inp")  # all abaqus test files

Data is cached in ~/.polyxios/ (override with POLYXIOS_HOME env var).

Direct download via curl / wget
