 March 11, 2007, 18:19 Meshing 2 separate objects #1 david Guest   Posts: n/a Hello, i'm currently trying to model the carriage of an armament on a wing mounted pylon in 2D, in GAMBIT. For this model, I have excluded the pylon (effects are negligable) so i'm modeling an aerofoil section, with a separate 'armament' section below it, in a specific postion. Just to give an idea of geometries, (Ca is the chord of the aerofoil, Cb is the chord of the Armament), the armament has a chord (Cb) 190%Ca. It is located 14.5%Ca below the Aerofoil, the centre of the leading edge of the armament is 65%Ca in front of aerofoil leading edge. Im having trouble meshing both of them- ok so I can make an easy tri-unstuctured mesh. But how would/could i go about making a structured accurate mesh? Any tips? Thanks in advance, Dave.

Ive been trying for hours now, and am not getting anything i'm sattisfied with! Thanks for your time.
