The objective of this CFD study was to assess the pedestrian wind comfort for different configurations of new buildings.

In one single step, a high-quality unstructured mesh was generated automatically by using NUMECA's HEXPRESS™/Hybrid software. The mesh contained 15 million cells and included dedicated blocks allowing for vegetation areas. The study then considered the impact of the vegetation by using porous media.

NUMECA's FINE™/Open was used to run steady 3D Navier-Stokes calculations. Post-processing included velocity contours at pedestrian level, as displayed on the picture above, as well as a detailed flow analysis including wind streamlines.
