Welcome to PHOENICS and CHAM
CHAM is an engineering-software company, located in Wimbledon, England.
Its full name is Concentration Heat and Momentum Limited.
Its business is, and has been since the 1970s, the provision of software and related services concerned with the computer simulation of processes involving the flow of fluids, together with the stresses and temperatures in solids in contact with them.
PHOENICS is its principal software product. This is a general-purpose package, first launched in 1981 and still pioneering new features.
One way in which it distinguishes itself from its competitors is the prominence it gives to RDI, i.e.
Relational Data Input.
Whereas other packages, and PHOENICS itself until 2007, allow the setting up of single-instance flow-simulation scenarios, the user of the new PHOENICS can set up classes of scenarios, of which sub-sets are selected by way of user-chosen parameters.
To enable users to exploit the power of RDI,
PHOENICS has been provided with a new front-end module, PRELUDE; and this, in conjunction with special-sector 'Gateways', enables users
to introduce easily the data which they understand from their special knowledge to be necessary, without having to attend to matters not of their concern.
Another of its unique features is:
which allows users to augment the built-in capabilities of PHOENICS by adding new ones of their own.
Whereas some other packages, as PHOENICS has done since its beginning, may allow users to do this by adding their
own Fortran or C coding, all the In-Form users has to do is express his intentions by way of formulae edited
(or placed via PRELUDE) in the input file.
PHOENICS has been taught to interpret the formulae, no matter how complex, and to carry out their instructions.
Of the many other unique features posessed by PHOENICS, only two more will be mentioned on this 'welcome' page.
The first is:
(an acronym formed from PARtly SOLid),which dispenses entirely with the laborious grid-generation task with which users of most other packages are burdened.
It enables the grid to be an easily-specified cartesian or cylindrical-polar one; PHOENICS then automatically adds the small number of additional polygonal cells, which are needed to fit objects of arbitrary shape.
The second is:
simultaneous flow and stress computation.
Whereas conventional wisdom has been that, for fluid-structure-interaction problems, it is obligatory to employ
two separate software packages, one for the fluid flow and the other (often finite-element based) for the
stresses in solids, PHOENICS handles both tasks simultaneously.
That is the end of CHAM's 'welcome' message. We hope that you enjoy your visit to our web-site; and we shall be glad to receive your advice as to how it can be made even more enjoyable.
