Urban CFD Visualization Platform

+

I am Sven Schneider, a researcher at HFT Stuttgart. On this platform an overview of + different visualizations schemes for urban CFD (Computational Fluid Dynamics) simulation data is provided.

+

The examples shown here were created during the iCity research project at HFT Stuttgart (University of + Applied Sciences Stuttgart). The CFD results were calcualted by my fellow colleagues at HFT Stuttgart.
