DISPLAY
A sphere of hot gas spreads flame into a cold combustible mixture
by diffusion, heat conduction and chemical reaction.
Gravity also causes relative motion.
The reaction is single-step, with rate dependent only on
reactedness.
The spherical geometry is contrived by use of special porosity
settings.
Dimensionless diffusion, reaction-rate and buoyancy parameters
may be varied.
PHOTON USE commands are supplied for display purposes.
