What it can do

  • Summarises a BDF model and lists nodes, elements, materials and properties.
  • Lists OP2 result cases and extracts stress and displacement results.
  • Checks mesh quality, returns the model bounding box and generates an analysis report.
  • Can write the loaded model back out to a new BDF file.

Limitations

  • Works on files only; it doesn't start Nastran, Patran or Femap.
  • The README's pip install name wasn't found on PyPI at this check; install from source.
  • No commits since March 2026.
