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 > - - — -----.



Note

Edge Bias
It is important to make sure that the edge divisions to this point are biased towards the center of the mesh: otherwise you may run into some problems later.

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