Hi,

I am trying to model onera M6 wing for ansys fluent anlysis. i am looking for the wing and the structure inside. I have come across Openvsp but am not sure if i can import that into ansys. anyone has the geometry please send it to me at hussan.muse@gmail.com. or away to do that. thanks

Hi Michael, Did you find the sharp trailing edge cad model of Onera M6? I have to make a grid which works on coarse one block c grid.

I have just drawn it according to dimensions given in AGARD report. I attached to this post for peope who are looking for in igs format.

Ali, your geometry is incorrect. The airfoils should be perpendicular to the 40.18% chord but you have placed them streamwise. This results in an incorrect thickness to chord ratio.

I have added thin trailing edge M6 geometries below for those who want it:

Ali,

You were actually correct with your model, I just found out that the airfoil coordinates that were provided were for the root airfoil instead of the Onera D wing section perpendicular to the 40.18% chord.

My model had a 6% thickness error. Apologies to all.

NASA now has a web page with the model available here: https://turbmodels.larc.nasa.gov/one...erics_val.html

NASA's Turbulence modeling resource website has also CAD geometry and grid generation codes.
