First, we will create the geometry of the airfoil. In the menu bar, go to Concept > 3D Curve. In the Details View window, click Coordinates File and select the ellipsis to browse to a file. Browse to and select the geometry file you downloaded earlier. Once you have selected the desired geometry file, click to create the curve. Click to get a better look at the curve.

...

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.

...

Click to generate the new coordinate system. In the Tree Outline Window, select the new coordinate system you created (defaulted to Plane 4 ), then click to create a new sketch. This will create a sketching plane on the XY plane with the tail of the airfoil as the origin. At the bottom of the Tree Outline Window, click the Sketching tab to bring up the sketching window.

...

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

...

In the final step of creating the geometry, we will break up the new surface into 4 quadrants; this will be useful for when we want to mesh the geometry. To begin, select Plane 4 in the Tree Outline Window, and click . Open the sketching menu, and select . Draw a line on the vertical axis that intersects the entire C mesh. Trim away the lines that are beyond the C-Mesh, and you should be left with this:

Next, go to Concepts > Lines from SketchsSketches. Select the line you just drew and click Base Objects > Apply , followed by . Now that you have created a vertical line, create a new sketch and repeat the process for a horizontal line that is collinear to horizontal axis and bisects the geometry.

...

Now, we need to project the lines we just created onto the surface. Go to Tools > Projection . Select Edges press Ctrl and select on the vertical line we drew (you'll have to select both parts of it), then press Apply . Next, select Target and select the C-Mesh surface, then click Apply .

Once you click , you'll notice that the geometry is now composed of two surfaces split by the line we selected. Repeat this process to create 2 more projections: one projection the line left of the origin onto the left surface, and one projecting the right line on the right surface. When you're finished, the geometry should be split into 4 parts.

Suppress the line bodies by right clicking in the tree. You only need the surface body to be transferred to the mesher.

The geometry is finished. Save the project and close the design modeler, as we are now we are ready to create the mesh for the simulation.

Go to Step 3: Mesh
