Closing Thoughts

CFD e/ists to ena!le new solutions to pro!lems$ reduce airplanedevelopment cost$ and reduce time to mar-et

CFD can allow you to safely e/plore areas of the flight regime

without putting a pilot at ris-

CFD can allow you to analy.e conditions for which physical

simulation is either very e/pensive or not possi!le$ such ashypersonic propulsion systems and full flight #eynolds num!er

testing

Accuracy$ ro!ustness and timeliness are the -eys to acceptance

and use in an industrial environment

Impediments applications that do not scale well &to 14445s of

processors with sufficient memory' this is scienceK resources to

run 1444s of flight conditions on 1445s of processors this is the

!usiness of engineering
