Vortex Analysis Library (VALIB).
Internal code: valib ; 2016
Technical parameters: Open source software package under the New BSD License
Economic parameters: The software contains state-of-the-art methods for vortex identification. These allow for better identification and visualization of vortices in applications such as flows around vehicles or in turbomachinery, leading to better insight into the vortical structures and potentially to more energy efficient designs.
