"Overnight computation of 6-point polar for landing configuration of a transport aircraft"
Transport aircraft in landing configuration, Hybrid mesh of approx 12 mill nodes:
(Heinz Jakob, EGAGM, April 2006)
- RANS computation
- M = 0.202, Re = 1.52 mill.
- α = 0.53° 4.75° 11.04° 15.18° 17.50° 18.07° - each 4000-6000 cycles
= 12.9 CPU-h on 48 processors Itanium
- 6 polar points, simultaneous computation = 6x48 = 288 processors in 12.9 hours
