Accuracy For Aerospace Applications
“Over the past years, we have used STAR-CCM+ to
predict the aerodynamic performance of both
commercial and military aircraft. In particular, we ran
cases from the 2nd Drag Prediction Workshop and
obtained excellent results compared with experiment.”
Matt Milne, QinetiQ
