FloVENT Products


Optimize HVAC airflows with fast, easy-to-use and industry-proven CFD simulation

Technical Specifications

FloVENT can be applied to buildings of all types and sizes:

  • Atriums, shopping malls and office buildings.
  • Theaters, airport terminals, storage facilities and warehouses.
  • Telephone exchanges.
  • Passenger comfort in vehicles.
  • Air quality and contaminant control in laboratories, research facilities, hospitals, clean rooms and underground parking lots.

Key Features

Model Creation

  • CAD-style, mouse-driven drawing board using simple draw, drag and drop operations to create and manipulate geometry.
  • Explorer-style project manager with drag-and-drop functionality.
  • Complete set of SmartParts (intelligent model creation macros).
  • Multi-level SmartParts (compact and detailed representations in a single object).
  • Structured Cartesian grid that can be “localized” and nested to minimize solve times and enable multi-scale modeling.
  • Full control of grid constraints for fine, local and global refinemen.
  • Object-associated grid that combines model creation and grid generation into a single step.

Solver and Design Optimization

  • Concurrent solution for convective, conductive and radiative heat transfer.
  • Fully automatic radiation exchange and view factor calculation.
  • Automatic solar loading boundary conditions.
  • Automatic treatment for heat gains and losses through glazing.
  • Solution termination optionally based on convergence of user defined monitor points.
  • Multi-fluids capability.
  • Ability to simulate either turbulent or laminar flow.
  • Definition in transient variation in terms of linear ramping, power increase, exponential increase, sinusoidal, periodic or imported .csv pointwise variations.


  • Particle animation and streamlines to visualize complex, 3D airflow.
  • Contour animation to visualize heat transfer paths.
  • Isosurfaces and surface temperatures.
  • Airflow representation by vectors or ribbons colored by temperature or speed.
  • Easy output of flow animations such as video (AVI format).
  • Dynamic particle tracking allowing a better understanding of complex flows.
  • Image texturing for photo-realistic visualization.
Airflow modeling gives engineers the luxury to consider several design options in the minimum amount of time. As a result, the final design is not based on a tentative approach, but is a result of a professional design process considering several options and selecting the optimum solution.
