Abstract
Numerical modeling of the wave interaction with coastal structures is a challenging
issue due to the multi-nonlinear phenomena involved, such as, wave propagation, wave
transformation, interaction among incident and reflected waves, run-up / run-down, wave
breaking and wave overtopping. Numerical models based on a Lagrangian formulation, like SPH
(Smoothed Particle Hydrodynamics), allow simulating complex free surface flows. This work presents
the new developments on a SPH numerical model for studies on wave-structure interaction made at
the National Civil Engineering Laboratory (LNEC). A new semi- automatic refinement
technique of particles was applied to reduce the CPU time. Simulations with a specific geometry,
a wave flume with a water chamber, were made regarding the application of this
technique. An analysis was made on (i) convergence with resolution, i.e. particle dimension and
(ii) semi-automatic refinement. Results were compared with the
solution obtained with the finer resolution.
