Special Features

IN-FORM allows the user to add new physical and numerical features on a case-by-case basis. This includes the input of problem-defining, solution-controlling and results-presentation data using the VR Editor. The user can do this by way of easy-to-write formulae which are interpreted by the code which then performs the specified computation

MOFOR (MOving-Frame-Of-Reference) models flows induced by bodies in motion. Uses for MOFOR range from the study of rotating machinery to the air flow over a ski jumper to help optimise posture for the reduction of drag and therefore maximise jump distance.

PARSOL (PARtial SOLid) enables PHOENICS to provide accurate flow simulations without the need to create time consuming unstructured grids. This makes PHOENICS accessible to the non-CFD expert as it obviates the need to learn the tools to create such grids.

Guaranteed Convergence
A guaranteed automatic convergence algorithm has been developed and included in the latest version of PHOENICS. Most CFD-code (ie not just PHOENICS) users have, until now, had to adjust convergence and relaxation parameters to achieve a converged solution. This development removes the need to run a case overnight to find that it shows no sign of convergence the following morning.

PHOENICS PLUS (GROUND coding) allows users to create customised environments to suit specific needs. Where an organisation does not have the resources, or inclination, to undertake development CHAM consultants will use PHOENICS PLUS to carry out the necessary work. If problems involve unique or ground-breaking physics this may not be included in the core of PHOENICS.

PHOENICS PLUS allows new physics to be added to augment or replace standard definitions. IN-FORM achieves this on a case-by-case basis whereas additions made using PHOENICS PLUS are available for all cases.

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.
