pyBladed

Purpose

This is the DLR-AE (Institute of Aeroelasticity, German Aerospace Center) Python wrapper for Bladed. It supports manipulation of Bladed models to support the automated setup of models (mainly through) the Bladed API as well as routines to access (binary) Bladed results. It is not meant to be a comprehensive tool that covers the full API functionality. Only required features have been wrapped so far.

Requirements

General

• OS: Windows (for Bladed)
• Python >=3.7 (for the Bladed API part, a 32-bit interpreter is needed)
• Bladed installed (we used v4.9)
• a Bladed license (e.g. the license dongle plugged in)
• the location of the Bladed API DLL is in your PYTHONPATH

Required Python packages

• numpy >= 1.12
• pytest >= 5.0 (for unit tests)
• pythonnet

Installing

• to use: pip install --user https+git://github.com/DLR-AE/pyBladed.git
• to develop
  • clone repository
  • pip install -e <local_repo_path>

Examples

The repository contains example data to demonstrate the functionalities of the result reader (clone it). They are also used to run unit tests.

Accessing data in Bladed results becomes pretty simple:

    from pyBladed.results.binary import BladedResult
    
    bladed_result = BladedResult(os.path.join('example_data', '2D'), 'powprod_12ms')
    bladed_result.scan()
    torque = bladed_result['Generator torque']
    power = bladed_result['Electrical power']

Running unit tests

Unit tests are currently only available for the result reader part. Simply run py.test in the root directory of the repository.
