Mapped Face Meshing

First, we will apply a mapped face meshing control to the geometry. In the Outline window, click on Mesh to bring up the Meshing Toolbar. In the Meshing Toolbar, select Mesh Control > Mapped Face Meshing. Making sure the face selection filter is selected , select all four faces by holding down the right mouse button and dragging the mouse of all of the quadrants of the geometry. When all of the faces are highlighted green, in the Details view Window select Geometry > Apply. Next, select

Edge Sizing

Next, we will apply edge sizing controls to all of the edges of the mesh. To begin, go to Mesh Control > Sizing. Next, click the edge selection filter . Select the following edges buy holding Ctrl and using the left mouse button:

Once the edges are selected, in the Details View Window select Geometry > Apply. Next, select Type > Number of Divisions. Change the Number of Divisions to 50. Select Behavior > Hard. We also want the mesh to have a bias, so select the first bias type: Bais > ----- — - -, and give the edge sizing a Bias Factor of 70. The Edge sizing should now look like this:

Notice that the element sizes get smaller towards the airfoil. This will give us a better resolution around the airfoil where the flow gets more complicated. Create a new edge sizing with the same parameters, but choose the remaining straight edges (see figure below). The number of divisions will still be 50, but now will be selecting a different biasing type by selecting the second Bias option: Bias > - - — -----.

Finally, create a third edge sizing, and select the rounded edges.
