Next, we need to create a surface from the curve we just generated. Go to Concepts > Surfaces from Edges. Click anywhere on the curve you just created, and select Edges > Apply in the Details View Window. Click to create the surface.



Create C-Mesh Domain

Now that the airfoil has been generated, we need to create the meshable surface we will use once we begin to specify boundary conditions. We will begin by creating a coordinate system at the tail of the airfoil - this will help us create the geometry for the C-mesh domain. Click to create a new coordinate system. In the Details View window, select Type > From Coordinates. For FD11, Point X, enter 1.

...

The first action we will take is create the arc of the C-Mesh domain. Click . The first click selects the center of the arc, and the next two clicks determine the end points of the arc. We want the center of the arc to be at the tail of the airfoil. Click on the origin of the sketch, making sure the P symbol is showing

...

To create the right side of the C-Mesh donain, click . Click the following points to create the rectangle in this order - where the arc meets the positive vertical axis, where the arc meets the negative vertical axis, then anywhere in the right half plane. The final result should look like this:

...

Now, we need to get rid of necessary lines created by the rectangle. Select Modify in the Sketching Toolboxes window, then select . Click the lines of the rectangle the are collinear with the positive and negative vertical axises. Now, select the Dimensions toolbox to dimension the C-Mesh domain. Click , followed by the arc to dimension the arc. Assign the arc a value of 12.5. Next, select . Click the vertical axis and the vertical portion of the rectangle in the right half plane. Also assign the horizontal dimension a value of 12.5.

...

Next, we need to create a surface from this sketch. To accomplish this, go to Concept > Surface From Sketches. Click anywehere on the sketch, and select Base Objects > Apply in the Details View Window. Also, select Operation > Add Frozen. Once you have the correct settings, click . The final step of creating the C-Mesh is creating a surface between the boundary and the airfoil. To do this, go to Create > Boolean. In the Details View window, select Operation > Subtract. Next, select Target Bodies > Not selected, select the large C-Mesh domain surface, then click Apply. Repeat the same process to select the airfoil as the Tool Body. When you have selected the bodies, click

Note

Selecting the Airfoil Body
Because the C-Mesh domain and the airfoil overlap, once you click in the vicinity of the airfoil ANSYS will select the C-Mesh domain but give you the option of selecting multiple layers

Select the layer that corresponds to the airfoil and the airfoil will be highlighted.
