AeroSim - CFD Platform for Wind Engineering¶

AeroSim is a GPU-accelerated CFD platform built for wind engineering simulations. It uses the Lattice Boltzmann Method (LBM) to model wind flow around buildings, structures, and terrain - running on NVIDIA hardware through the AeroSim cloud or on your own infrastructure.

Simulations are validated against wind tunnel data and designed to follow EN 1991-1-4 terrain exposure categories.

Simulation Capabilities¶

AeroSim covers the core wind engineering analysis workflows used in building design and urban planning:

Building pressure coefficients - Cladding and structural wind loads on buildings, validated against wind tunnel data
Pedestrian wind comfort - Wind speed ratios at pedestrian level for urban environments and building surrounds
Topography wind effects - Speed-up factors over hills, escarpments, and complex terrain profiles
Atmospheric boundary layer (ABL) setup - Inflow profile calibration for terrain roughness categories I-IV per EN 1991-1-4

Platform Components¶

This documentation covers the full AeroSim platform and its associated tools:

Nassu: the LBM solver engine that runs simulations on NVIDIA GPUs
Validation: validation portfolio with results compared against wind tunnel and reference data
CFDmod: Python API for pre- and post-processing of simulation cases
