One can also perform a mesh refinement study. Duplicate your project, import the new refined mesh (found here), "Clear Generated Data" for Results cell, refresh the project and launch Fluent. Remember to use Parallel (2, 3 or 4 cores, no more than that) if available. Also, compute the initialization from farfield1. Run the simulation for about 2000 iterations. Use this new mesh.msh file an run it.
Make a test refining the mesh (provide geometry?) and check reduced mass imbalance, check change in plots?

Maybe making geometry with actual airfoil? Scale up?
This is the new velocity contours.
The (absolute value of) mass imbalance between farfield1 and farfield2 also change, dropping to about 1.48e-9. This is a reduction of exactly 5 times! Yay.
Note: this new mesh uses completely different meshing techniques. The ideal would be using the very same method as before. This new mesh is more "professional made" than the previous one.
