Abstract:
The talk covered several issues motivated by a practical engineering wave propagation problem: real-time evaluation of wave agitation in harbors. The first part, presented the application of a reduced order model in the framework of a Helmholtz equation with non-constant coefficients in an unbounded domain. The second part of the talk addressed two questions, which continuously emanate in advanced computational engineering: are high-order approximations better/worse than low-order ones? and can Discontinuous Galerkin (DG) be more efficient then Continuous Galerkin (CG)?
