Wind engineering study
What it is
Computation of wind speeds over the site plateau. The topographic factor corrects the wind speed reaching structures near slopes, hills and valleys. Essential for sites on complex terrain.
When you need it
When the site sits on or near slopes, hills, escarpments or valleys, where the terrain speeds the wind up and a single code factor does not capture the real wind field reaching the structure.
What we deliver
How we do it
Build a digital terrain model of the site plateau and the surrounding relief.
Run simulations across the governing wind directions over the terrain.
Compute the topographic factor and map the wind speed-up over the site.
Deliver the corrected wind field and structural recommendations per the applicable wind standard.
Real project
Logistics development
Wind speeds computed over the site plateau of a logistics development, replacing a blanket code factor with the real topographic speed-up. The more accurate loads cut structural material across the board.

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.
