In the solver
What it is
Resolve the unsteady wind around a building and extract external pressure coefficients (Cp) across the full envelope - the loads that cladding, glazing and curtain-wall design depend on.
Typical run
Indicative single-GPU estimates - they scale with domain size and the accuracy you need.

How it works
Import or build the building and its surroundings; the CAARC benchmark preset is a ready starting point.
Set a realistic atmospheric inflow with the SEM inlet.
Run LES for the governing wind directions and record surface pressures over time.
Extract external pressure coefficients (Cp) across the envelope, separated by zone.
What you get
Why you can trust our results
We are not a physical wind tunnel - we are a CFD specialist whose results are validated against wind tunnel measurements. AeroSim is an international reference in computational wind engineering.
