+Class
+ Foam::objectives::objectiveNutSqr
+
+Description
+ Objective qualitatively quantifying noise through the integral of the
+ squared turbulent viscosity over specified cellZones. Requires the adjoint
+ to the turbulence model to be incorporated into the optimisation loop.
+
+ Reference:
+ \verbatim
+ Objective function initially presented in
+
+ Papoutsis-Kiachagias, E. M., Magoulas, N., Mueller, J., Othmer, C.,
+ & Giannakoglou, K. C. (2015).
+ Noise reduction in car aerodynamics using a surrogate objective
+ function and the continuous adjoint method with wall functions.
+ Computers & Fluids, 122(20), 223-232.
