A Lagrangian–Eulerian procedure for the coupled solution of the Navier–Stokes and shallow water equations for landslide-generated waves

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
This work presents a partitioned method for landslide-generated wave events. The proposed strategy combines a Lagrangian Navier Stokes multi-fluid solver with an Eulerian method based on the Boussinesq shallow water equations.

An ellipsoidal particle–finite element method for hypervelocity impact simulation [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 2003
AbstractA number of coupled particle–element and hybrid particle–element methods have been developed for the simulation of hypervelocity impact problems to avoid certain disadvantages associated with the use of pure continuum‐based or pure particle‐based methods. To date these methods have employed spherical particles.
