Oscillating airfoil meshing(hybrid)
 

Hello,

Currently, I am trying to simulate 2D oscillating airfoil with Fleunt.
And I am trying to create hybrid mesh. I have been trying this more than 3weeks but I couldn't get great result:(

First i created geometry and farfield. then I used curve mesh setup to get the following mesh.

But when I output this mesh Fluent, I get critical error. Since I am new user and not familiar with Icem and Fluent, I am missing some basic steps.

Please can anyone address basic steps to help me? Here are my geometry and mesh file. Thanks for any help.
