HEVACOMP CFD MODULE for Building Services Applications
Hevacomp (formed in 1981) is the firmly established UK market leader in building services design
and CAD software. Hevacomp software is acknowledged as the industry standard, with over 2000 user
sites – the largest user base of any developer in the building services field. In line with the
company's vision to bring Dynamic Thermal Simulation and CFD analysis within easy reach of every
engineer, Hevacomp has joined forces with CHAM to link Hevacomp's new Dynamic Thermal Simulation
package to CHAM’s PHOENICS/FLAIR CFD solver.
The room geometry information, including the surface temperatures and convection coefficients,
together with room objects like diffusers and heat sources, is created parametrically in Hevacomp's
new Simulation module. The complete input file is then passed to the CFD solver provided by CHAM.
A key issue is the accurate modelling of diffusers and grilles. CHAM in co-operation with Hevacomp
has implemented diffuser objects based on ASHRAE research.
The new Hevacomp Simulation package enables detailed heat gain simulations with detailed shadow
analysis, heat loss simulations, summertime temperatures including mixed mode ventilation studies,
overheating frequencies and extensive energy consumption and carbon calculations studies.
Prices start from £500 per year.

Hevacomp incorporates a number of air distribution devices with manufacturers' data. It has an
equipment library for localising heat gains, as well as a furniture library. When a CFD module 'project
file' is written by Hevacomp, all the boundary conditions are automatically set-up as a result of the
Design Simulation (i.e. convection coefficients and surface temperature as well as the room surfaces
geometry). The user does not have to set these manually.
The simulation engine for both PHOENICS/FLAIR and Hevacomp's CFD module is the same. The pressure,
velocity and temperature variables are solved and reported in the same manner.
Whilst the Hevacomp CFD module is a very fast and efficient process for producing the CFD input file,
the shape and complexity of the room model is defined both the options solely available within Hevacomp's
CAD environment, as the PHOENICS/FLAIR (VR Editor) pre-processor is disabled in this version.
Similarly, Hevacomp's CFD simulations solutions are currently limited to a single room. With
PHOENICS/FLAIR any shape with any complexity can be setup, incorporating both internal and external
For users with additional flow-modelling requirements, CHAM offers a natural progression from Hevacomp's
CFD module onto PHOENICS / FLAIR. Such requirements might include, but are not limited to:-
- Creating complex geometry, or importing from CAD;
- Problems involving external flow scenarios, wind profiling or pressure loading;
- Cases involving pollution, fire hazard, radiation, smoke, or sprinklers;
- Extended HVAC studies, or ISO-standard comfort indices; etc.
Hevacomp customers purchase PHOENICS/FLAIR under preferential terms!
A description of PHOENICS / FLAIR can be found in the FLAIR brochure or

CHAM is looking for one or two new Project Engineers. Please see the Vacancies Section of this website for full information.
Professor Brian Spalding received a degree of Doctor of Science honoris causa from Imperial College at the beginning of May. Brian has been associated with IC from 1954 when he was invited to join from Cambridge. He started as Reader in Applied Heat, in 1958 was appointed to the Chair of Heat Transfer and, subsequently was also Head of the Computational Fluid Dynamics Unit. He remained Professor of Heat Transfer and Head of CFD until his retirement in 1988. The doctorate was awarded for services to science and to CFD of which he is a founding father.
ACADS-BSG, CHAM's Agent in Australia, will be exhibiting PHOENICS/FLAIR at the Melbourne Convention and Exhibition Centre, May 20-22 on Stand 17, at ARBS 2014. They will be demonstrating examples of car-park fires and applications relevant to the HVAC industry. Click here for further information.
Shanghai Feiyi has arranged a user meeting on May 20,21 2014 in Hangzhou city, Zhejiang Province where the Beta-release version of PHOENICS-2014 will be demonstrated. Click here for further information.
