In the solver
What it is
Capture the unsteady wind loading on a tall or slender structure and turn surface-pressure time series into global static and dynamic forces - and per-floor accelerations for occupant comfort.
Typical run
Indicative single-GPU estimates - they scale with domain size and the accuracy you need.

How it works
Model the building and surroundings and run LES to capture the unsteady wind loading.
Export pressure time series across the envelope.
Integrate them into global static and dynamic forces on the structure.
Combine with the structure's modal properties for per-floor accelerations.
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.
