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

Clone the git-repo first:

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

cd OpenGlider
pip install -e .

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

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

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

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

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

./testall.py

Or use -a flag to also run visual tests

./testall.py -a

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

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
