Numerical simulation of the Peregrine system with different time-stepping methods and using or not artificial dissipation as stabilization.
Javascript desactivado
Optimization of the object's shape to maximise the height and steepness of the wave using Ipopt. No energy criterion is used here and the optimal shape is therefore the biggest and steepest one allowed in the set of admissible shapes.
Javascript desactivado
Same optimization of the object's shape as in the previous simulation, but using Dolfin-Adjoint and a truncated Newton algorithm. The convergence is slower but tends to the same result.
Javascript desactivado
Orbital view of the initial shape of the moving object to be optimized. We are only interested in the optimization of the right half of the object.

Stationary solution of the Peregrine model in 2D and 1D, and comparison between an implicit and a Crank-Nicholson time-stepping method.

Cross-section of the previous simulation for the transport equation. The red curve is the real solution.
