AVL and Silicon Graphics Prism deliver a complete scalable compute and
visualization solution for engine engineering, from the pre-processing phase
(project management, model preparation and mesh movement) to the solver (fully
unstructured technology for arbitrary cell types, true multiphase
capabilities, comprehensive set of internal combustion-engine specific spray
and combustion models ) to the post-processing (multiple cuts, surface values,
particle tracing and animation director) .

A branch of mathematics that studies the use of repeated discrete operations to find approximate solutions to continuous equations.
