Abstract
Wave attenuation by elastic structures is a challenging issue when studying shoreline protection subjected to waves and erosion. For this purpose, a fully Eulerian method is then developed to solve the problem of fluid–elastic structure interactions for incompressible flows. The specificity of the proposed approach is to use a combination of a reinitialization technique for the interface and linear extrapolations for the deformations to prevent numerical instabilities for the computation of the elastic forces. First, we verify and validate our approach on several test cases. Next, we apply this method to illustrate the capacity of the model to study the wave damping phenomenon by a single or several elastic structures.
