 April 5, 2001, 10:52 Airfoil Meshing Scheme in Gambit #1 J. Weiler Guest   Posts: n/a I am attempting to mesh an RAE 2822 airfoil in Gambit and am encountering great difficulty. I read that the most accurate means of meshing the free stream and boundary regions are by modeling the free stream with the same shape as the airfoil. I have scaled my airfoil up to create a free stream that is at least 10 chord lengths away from the airfoil surface, but I am having trouble getting the quality that I need (i.e. creating mesh areas that will allow me to use a Quad/Map scheme). Any advice or insight would be most helpful. Thanks.

We succeeded to create O-mesh and H-meshes for the same airfoil using Quad/Submap scheme combined with one or two regions meshed with Wedge Primitive scheme. This way you can easily control the density of the mesh without using boundary layers. The triangular scheme was much havier, quite difficult to adapt and the hell of the convergence. Cheers, Yulia

 June 27, 2010, 19:25 Airfoil rotating w.r.t central axis #5 New Member   SOhail Join Date: Jun 2010 Posts: 16 Rep Power: 7 Hi, I am trying to run simulation (2D) for 3 bladed NACA 0012 airfoil in vertical motion with respect to central axis using gambit and fluent. I know how to create mesh for single airfoil and run simulation on it, but i don't know how to create mesh for airfoil and to rotate it in fluent. I would be glad if anyone could help me out. Here is a youtube video of what i actually want to do. Please help me out guys, its part of my thesis. http://www.youtube.com/watch?v=1eyEtzdHDEE Regards.

HI
I am also looking for same, do you got any information about rotating the airfoil in fluent. I would be glad if you could help me out.

for rotating airfoil in fluent u must used udf and compile it in fluent.
for some information see fluent udf manual(dynamic mesh).
