OpenGlider

A future open source paraglider design software (still a WIP)

Try It

Clone the git-repo first:

git clone https://github.com/hiaselhans/OpenGlider.git

Install with pip

cd OpenGlider
pip install -e .

Or manually install all dependencies (using distro-repos, easy_install or pip)

• ezodf2
• dxfwrite
• scipy
• (svgwrite)
• (vtk)

Install with pixi

if you have pixi installed just launch pixi and run this command pixi run freecad to launch freecad with openglider installed.

Install with conda

We are providing packages of OpenGlider and dependencies via conda. To install conda download miniconda and follow the install instructions. Once you have a working base-environment you can create a new environment for openglider:

conda create -n openglider openglider freecad meshpy -c conda-forge

Documentation

Every module inside openglider should have a README where the functionality is documented.
Please have a look at the base module.

Also have a look at the gui-tutorial

Unittests and Visual Tests

To run all unittests, run this from the main directory:

./testall.py

Or use -a flag to also run visual tests

./testall.py -a

Development Screenshots

While still being in an early status, here are a few screenshots showing progress made so far:

Roadmap

The plan is to build on the following technologies:

• Python (link)

• self-coded panelmethod (VSAERO) and/or apame implementation (link) for quick 3D-calculation (see parabem)

• OpenFoam obj-file CFD export

• paraFEM - Explicit non linear FEM (membrane, truss) for line forces and deformation analysis

• FreeCAD (Open-Source Cad, written in c++ with python API

• VTK - visual toolkit for 3d-output

• Code_Aster FEM export (http://www.code-aster.org) - maybe calculix as we've done already, but it does currently not support membrane elements)

• xfoil//Pyxfoil for 2D-foil calculation (http://web.mit.edu/drela/Public/web/xfoil/) (http://www.python-science.org/project/pyxfoil)

It will take some time, if you want to help, feel free to do so!

Using some older code, we already created a few prototypes which can be seen on http://www.booya.at
