EXPLOITS makes use of the PHOENICS Virtual-Reality Interface, which
requires only basic keyboard-and-mouse skills.
This VR system is of the "non-immersive" kind, which means that no
special gloves or head-sets are required.
The next picture shows the control screen which is presented to the
user.
The various buttons and arrows permit the view to be controlled, and
the various objects to be moved, re-sized, deleted, or duplicated.
This is an illustration of how objects of various shapes
and sizes are brought in and positioned.
Note the control buttons around the edges of the screen

Placing the mouse on the appropriate arrows enables the objects
to be viewed from various angles like this ...
Angle 2
Grids can be displayed and modified and viewed from various
viewpoints The "top-view" box
assists orientation
The materials of which solid and fluid objects are composed are
selected from lists which can be called into the dialogue boxes.
A "fluid object" could comprise, for example, a region in which
there exists a gas mixture with a particular fuel/air ratio.
The EXPLOITS Virtual-Reality Interface allows the user to select
models of ignition, laminar flame propagation, turbulent mixing and
turbulent combustion, through the "domain" dialogue box.
If the user makes no selection, the built-in defaults, which are
usually satisfactory, will be employed.
Among the "objects" which the EXPLOITS interface can call into its
virtual-reality world are inlets, outlet apertures, and sources of
mass, momentum and energy.
They can be named, located, and given qualitative and quantitative
attributes in the same "dialogue-box" manner as employed for solids.
The apertures may be of the "bursting-panel" character; and indeed
the flow rate through them can be any non-linear function of
pressure difference and time.
They may also consist of sources of gas or liquid which become
active after the start of the explosion as a cosequence of the
passage of the flame, or of the pressure wave which precedes it.
7.1 Geometrical-data input
"Clicking" on an object brings a
"dialogue box" on to the screen.
This enables a name to be typed,
and some data to be altered.
