FloVENT® Optimizing Airflow Design by Simulation Mechanical Analysis

3D Airflow Modeling Software Overview Since 1988, our Mechanical Analysis Division has played a pioneering role in the simulation of airflow in and around buildings by delivering high-quality analysis software for designers. The result is powerful Computational Fluid Dynamics (CFD) software called FloVENT, which predicts 3D airflow, heat transfer and contamination dispersion in both internal and external environments. FloVENT’s fast and easy-to-use menu system is designed specifically for engineers involved in the design and optimization of heating, ventilating and air conditioning (HVAC) systems....

“ Using FloVENT, we can review a number of design scenarios early in the development cycle, which helps to reduce bottlenecks and improve engineering performance. ” Ian Matthews, Engineer, Buro Happold
