3D Airflow Modeling
Software |
Overview
Since 1988, Flomerics has played a pioneering role
in the simulation of airflow in 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 optimisation of heating, ventilating
and air conditioning (HVAC) systems. FLOVENT can
be applied to buildings of all types and sizes.
- atriums, shopping malls and office buildings
- theatres, airport terminals, storage facilities
and warehouses
- telephone exchanges and data centres
- passenger comfort in vehicles
- air quality and contaminant control in laboratories,
research facilities, hospitals and underground
car parks.
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. This can save on capital and
running costs, save time on correcting mistakes further
down the design route and save time on commissioning.
Whether you choose to license FLOVENT for inhouse
use or to employ Flomerics’ FLOVENT airflow
modeling consultancy, you can meet the daily challenges
of predicting airflow patterns and thermal effects,
maximizing contamination control, and reducing operating
costs more confidently and productively than ever
before. |
Why Perform Airflow Modeling?
No matter how complex your airflow
application is, modeling enables you to
understand it more comprehensively
through the medium of virtual reality
and computer 3-D animation. As a
result, you can:
- Thoroughly understand the
multiple, interacting factors that
influence airflow.
- Optimize design calculations of air
volume and set point temperatures
to enable dramatic savings in capital
investment and system operating
costs.
- Confidently predict and eliminate
airflow problems or hazards early in
the design process before building
or renovation begins.
- Effectively troubleshoot airflow
problems or hazards in and around
existing facilities to ensure fast
resolution with minimum
downtime.
- Dramatically reduce the time and
cost while dramatically increasing
the value of physical airflow testing
and measurement.

Model Creation
SmartParts
FLOVENT features the most complete and
technically advanced model creation
environment for airflow modeling design.
Models that range in scale from diffusers, heat
exchangers and enclosures are assembled quickly
from a complete set of SmartParts (intelligent
model creation macros) that are supplied with
FLOVENT. SmartParts capture modeling expertise
that has been developed within Flomerics over
the past 15 years to streamline model creation,
minimize solve times and maximize solution
accuracy.
Integration with CAD
FLOVENT also features the industry’s best solution
for integration with CAD software. Native data
from Pro/Engineer, Autodesk inventor,
Solidworks, and other CAD software can be
imported into FLOVENT. Unlike other CAD to
analysis interoperability solutions, FLOVENT
automatically prepares the geometry for efficient
and accurate analysis.
Grid
FLOVENT grid is structured-Cartesian - the most
stable and numerically efficient type of grid
available. The ability to localize is also included
for finer resolution where it is needed,
minimizing solution time and avoiding the
penalty of grid cells that “bleed”.
Grid in FLOVENT is associated with SmartParts
and is generated as part of the model assembly
process with refinement under user control. This
methodology is intuitive and straightforward
enabling engineers to focus on design rather
than analysis.
Gridding is instantaneous and reliable in FLOVENT
as compared to traditional tools that require
significant time and expertise to master. Finally,
FLOVENT is the only analysis software with
object-associated grid that eliminates re-gridding
for each model modification. |
SOME KEY FEATURES
- 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 refinement
- Object-associated grid that
combines model creation and grid
generation into a single step

Solver and Design Optimization
Automatic Sequential
Optimization
SmartPart-based modeling and structuredcartesian
grid enable a feature called ‘automatic
sequential optimization’ that is unique to
FLOVENT. This allows users to specify a design
goal and then let FLOVENT do the hard work of
finding the right combination of design variables
that meet the goal. Common applications of this
feature include optimization of diffuser locations
and discharge velocities as well as other design
scenarios.
Design of Experiments
Parametric Studies
As an alternative to automatic sequential
optimization, a design of experiments (DoE) can
be constructed that will automatically analyze
the full range of all possible combinations of
parametric variations. These models can be solved
on a distributed network of computers using the
unique ‘Volunteer’ solution technology.
Solver
For over 15 years, the FLOVENT solver has
specifically addressed heating, ventilation and air
conditioning (HVAC) applications. The solver,
based on a cartesian gridding system results in
the most accurate results possible and the
fastest solution time per grid cell. Massive
disparency in geometric length scales are
resolved using the unique ‘localized-grid’
technique which allows for integrally matched,
nested, non-conformal grid interfaces between
different parts of the solution domain. The
conjugate nature of heat transfer is concurrently
solved using a preconditioned conjugate residual
solver together with a flexible cycle multi-grid
solution technique. Pragmatic, unique and
accurate solution termination criteria produce
useful results in engineering, not academic, time
scales.
Transient Analysis
The powerful transient analysis capabilities in
FLOVENT also allow for prediction of a number
of different transient behaviours. For example an
accurate prediction of smoke or contaminant
dispersion can be calculated both internally and
externally. Various scenarios can be investigated
by changing the concentration of the smoke or
gas in relation to elapsed time |
SOME KEY FEATURES

conductive and radiative heat
transfer

and view factor calculation
- Automatic solar loading boundary
conditions

and losses through glazing

or laminar flow (turbulent models -
revised algebraic, LVEL algebraic,
Standard k-e, revised k-e)
- Definition in transient variation in
terms of linear ramping, power
increase, exponential increase,
sinusoidal, periodic or imported
.csv pointwise variations
