AIJ urban wind environment benchmark cases (A–M)
Collection · 12 parts Benchmark Lab 12 parts
The Architectural Institute of Japan (AIJ) urban wind environment benchmark suite: wind-tunnel and field data for cases A–M, from a single high-rise building and cube arrays to real districts such as Shinjuku and Niigata, many with STL geometry. Widely used to validate CFD for pedestrian-level wind and dispersion.
