End face boundary conditions required for a 3D analysis of a wing?

In the NACA 4415 airfoil problem, end faces are deleted mentioning that details of the simulation at the wing tip were not required. I am interested in performing a 3D analysis so please tell me what are the boundary conditions and other changes required to be made for the analysis.

Thanking you in Anticipation.

Keep the wing tip

For a 3D simulation keep the wing tip and apply the standard wall boundary condition.
