**2.4 Adding wake boundary conditions and the Kutta condition**
Two additional conditions must be prescribed to allow lifting configurations to generate aerodynamic loads. Firstly, boundary conditions must be enforced on wake surfaces and secondly, the Kutta condition needs to be enforced on the trailing edge of any lifting surfaces. The wake boundary conditions are added using the dart::Wake class as,

```python
pbl.add(dart.Kutta(msh, 'te', 'wake_', 'body', 'field', is_linear))

where `'te'` is the name of the physical group of the mesh containing the trailing edge of `'body'` and the flag `is_linear` indicates whether the linearized Kutta conditions must be used. Note that the wake surface does not need to be aligned with trailing edge bissector because dart::Kutta adds a supplementary term on the elements touching the trailing edge that correctly computes the local flow direction.
