Mesh

Open the Mesher

To open the mesher, double click the Model box box in the Project Outline window. This will load ANSYS Mechanical. You should now be able to see the airfoil geometry.

...

The first thing we are going to need to do when the mesher opens is specify the thickness of the airfoil walls. In the Outline window, expand Geometry and select Part 1 Surface Body. In the Details window, change the thickness to 0.01 m. We also need to specify the material. In the Outline window. In the Details window, select Material > Assignment > Al 6061-T6. The material has now been specified.

Mapped Face Meshing

To apply a mapped face meshing, first click on Mesh in the Outline window. This will bring up the Meshing Menu Bar at the top of the screen. Next, select Mesh Control > Mapped Face Meshing. Select the 2 faces of the mesh by holding down the left mouse button and dragging over the entire geometry. In the Details window, click Geometry > Apply - it should say 2 faces are selected.

Edge Sizing

In the Meshing Menu, click Meshing Control > Sizing. Click the edge selection filter . Select the 4 curved edges on the outside of the geometry that make up the shape of the NACA 0012 Airfoil as the picture shows:

...

In the details window, select Geometry > Apply, and select Type > Number of Divisions. Change the Number of Divisions to 50. Also, change Behavior > Hard.

Next, create another Edge Sizing, and this time, select the 2 edges at the very front and very back of the airfoil that run along the wingspan, as the picture shows:

...

Again, in the Details window change the settings such that Type > Number of Divisions and Behavior > Hard. This time, change the Number of Divisions to 20. Generate the mesh by selecting Mesh > Generate Mesh.
