Re: [Openrocket-devel] Custom shaped nose cones?

[Richard G. <ri...@rd...>]

I don't think this would be possible. OpenRocket uses interpolation from
experimental data of different nose cone shapes in the aerodynamics
calculations. Simulating an arbitrary nose cone would require going to a
full comupational fluid dynamics simulation.
