We provide CFD analysis software, support, training and consulting to a broad range of industrial and engineering companies. We try to combine our experience in understanding complex CFD applications and our expertise in numerical methods in order to develop innovative and cost effective solutions to our clients. We provide consultancy work in several fields of CFD (fire in tunnels, multiphase flows, atmospheric dispersion, condensation/evaporation, critical fluids, numerical modeling of crystal growth (gas & liquids), HVAC...) as well as specialized CFD codes such as PHOENICS, FLAIR and customized codes. We are distributors of CHAM products in the US since 2012 and in France since 1996. Our highly trained professionals in computational fluid dynamics as well as a wide network of partners outstand our services and products in order to help you solve specific issues, minimize your efforts while maximizing your efficiency and thus achieving excellence.

CHAM (Concentration Heat and Momentum Limited), is a world-leading consultancy and software house specializing in computer simulation of fluid-flow and heat-transfer processes; it was founded in 1974 by Professor Brian Spalding FRS FREng. CHAM's HQ is in Wimbledon, London, England, with a subsidiary in Japan and agencies worldwide. CHAM spearheaded applying CFD to problems in engineering equipment and the environment. Use of PHOENICS (CHAM's innovative general-purpose CFD software), sharpens the competitive edge of companies and industries worldwide. CHAM has a team of experienced professional engineers, led by its founder and has developed special-purpose industry–specific graphical environments for several important market sectors.
FLAIR-EFS is a reduced-cost subset of FLAIR for users concerned only with external environmental conditions surrounding buildings and other structures. Object types concerned with internal flows (ie jet fans, diffusers, spray heads) or fire modelling have been removed.
The normal mesh generator is replaced by a system based on size of building(s) being modelled, which are always placed centrally in domain. Domain size is based on multiples of maximum building height.
Users set a minimum cell size. FLAIREFS meshing dialog is shown below:
FLAIR-EFS can show Pedestrian Comfort information including:
- Wind Amplification Factors.
- Probability of the wind speed to exceed a set threshold value.
- NEN8100 Dutch standard for Wind Comfort and Wind Danger in the Built Environment.
Given a table of wind direction and wind speed probabilities for each direction, it is possible to create an average wind speed by running for each wind direction in the table, and then summing absolute velocities multiplied by sector probabilities. The PHISUM utility can be used to sum output files from individual runs.
Our CFD software offer unrivaled benefits to many industries and applications, including:
