Like FEA the CFD methods break down the fluid continuum into many 'cells' whose interactions can be described by relatively simple equations.

The applications and capabilities of the CFD code used by Engenuity include; multi-phase, combustion, unsteady flows, moving boundaries, supersonic aerodynamics, and particulate erosion.

Almost any physical parameter can be recovered including pressures, velocities, forces, temperatures and mass fractions of individual species. CFD can study conditions which would be impossible, or impractical to investigate physically, providing realistic values where only estimates were available. It can cost effectively support physical testing, reducing time-scales and providing information more enlightening than any wind tunnel method.
