Wind Engineering

Designs of skyscrapers, bridges, stadiums and iconic landmarks around the world grow more complex with each new project. As a result, engineers must carry out more and more complex analyses on these structures to ensure strength and safety. Key considerations include how a building responds to its environment as well as the effect that the structure will have on the space around it.

Understanding the aerodynamics of a building is much more efficient and accurate when virtual modeling is used. Assessing the structural load imposed by the wind is a priority. But simulation software can tell designers much more, including the effectiveness of natural ventilation in a sustainable building design, the transport and dispersion of exhaust gases and other pollutants, and pedestrian comfort at ground level.

Software from ANSYS has the ability to perform such analyses on all kinds of structures. ANSYS tools offer engineers a greater understanding of the aerodynamics of structures while providing regulatory authorities with vital environmental impact information, particularly if the building falls outside standard design codes.

Using virtual modeling, designers can carry out simulations on large and small projects alike. The comprehensive multiphysics capabilities built into ANSYS software enable analysis of isothermal and buoyant wind flows, using a wide range of turbulence models and fluid–structure interaction. Because such analysis provides a variety of options quickly and efficiently, simulation reduces the risk of faulty construction and increases the probability of project completion on time and within budget, satisfying all regulatory requirements.
