hi,all, anyone has this paper or provide info where to get it?

Batina, J.T., 1989, "Unsteady Euler Airfoil Solutions Using Unstructured Dynamic Meshes,"AIAA Paper 89-0115, AIAA 27th Aerospace Sciences Meeting, Reno, NV, USA

If everything else fails, try here: http://www.lindahall.org/pubserv/aiaa/dispatch.htm

Zhang,

There is a paper in AIAA J, which might be the same and may be easier to get.

Batina, J.T., "Unsteady Euler Algorithm with Unstructured Dynamic Mesh for Complex-Aircraft Aerodynamic Analysis", AIAA J. v29 n3, pp 327-333, March 1991 (recived May 8, 1989).

Well, I've got a copy from AIAA Jounal

thanks.
