Modal Analysis of Airplane Wing in ANSYS

The wing is uniform configuration along its length and its cross sectional area is defined to be a straight line and a spline as shown. It is held fixed to the body of the airplane on one end and hangs freely at the other. The objective of the problem is to find the wing natural frequency and mode shapes.
Approach and assumptions
The side of the wing connected to the plane is completely fixed in all degrees of freedom.
The wing is solid and material properties are constant and isotropic.
Solid modeling is used to generate a 2 D model of the cross-section of the wing.
Create a reasonable mesh and extrude the cross-section into a 3D solid model which will automatically be meshed.
Young Modulus 38 GPa
Poisson ratio, 0.3
