 The non-hydrostatic version of \telemac{3D} is used.
 To solve the advection, the method of characteristics (scheme \#1) is used for
 velocities.

+The conjugate gradient (option 1) combined with preconditioning = 34
+= 2 $\times$ 17 is used for solving PPE as more efficient than GMRES (option 7)

 The time step is 0.5~s for a simulated period of 300~s.
