GH_Wind

Wind Simulation (FFD) plugin for Rhinoceros Grasshopper.

Please refer to this publication for citation: Waibel et al. (2017). It also includes validation and comparison studies with OpenFOAM and wind tunnel experiments.

Installation

The current build can be found in the Tutorials folder. Place FastFluidSolverMT.dll and GHWind.gha into your Rhino Grasshopper components folder and you are good to go.

Examples

Try out the *.gh and *.3dm files in the Tutorials folder as examples. The folder also contains two optimization examples (200528_Highrise.ghand 200528_Breathability.gh) from Waibel et al. (2019). See the paper for a description of the problems.

Airflow optimization. Left: Surface pressure minimization of a high rise building. Right: Improving natural ventilation of 4 buildings. From: Waibel et al. (2019)
