This is the second in a series.  You can start the series here.   The series follows my journey figuring out how to use OpenFOAM for something more than repeating tutorials that already exist!    Sometimes that journey gets a little rocky!   :)

The Final Wing Design

The setup is similar to the 2D cylinder in last episode.  This time, I used the Airplane Design Workbench in FreeCAD (if you don't see it listed, check your Tools -> Addon Manager).  I created a wing with two segments, using the provided NACA 2412 airfoil.  The specifics are not terribly important; my goal was to get a mesh to compute and get the OpenFOAM solution to converge.

The CFD setup was straightforward:  steady-state, incompressible flow.  I created a 'Symmetry' constraint on the near wall.  The far, top and bottom walls had an inviscid constraint.  The flow went in the +X direction, and the appropriate faces constrained as Inlet and Outlet.  The wing surfaces all had a viscoud (no-slip) constraint.

​Taking the results into ParaView, I learned what the Clip filter does!  Then I added arrow glyphs to represent velocity.  I did not figure out how to avoid the short, stubby arrows, but that is a problem for future me.
