Also note that the aerodynamic prediction portion of the RASAero II software
has been used to generate aero data for launch vehicles run on other ascent to
orbit flight simulation programs. In fact the last update of RASAero II
(Version 1.0.1.0) included changes to improve models specifically for launch
vehicles.
From the RASAero web site for the RASAero II Version 1.0.1.0 update:
http://www.rasaero.com/dl_software_ii.htm
"Added extension to power-on base drag model for very large nozzle exit
diameters at supersonic and hypersonic Mach numbers, with the nozzle exit area
filling a large portion of the rocket base area, for more accurate power-on
drag coefficient (CD) predictions for first and second stages of satellite
launch vehicles."
