              Concrete block modeled by Smoothed Particle Galerkin​ (SPG)

              Water modeled by Smoothed Particle Hydrodynamics (SPH)

SPG with bond-failure model works very well for semi-brittle material. Particle-based multi-body contact algorithm has good performance in dealing with SPG-SPH interaction as well as self-contact of SPG concrete part. This new feature combining SPH fluid and SPG solid makes it possible to solve some very challenging problems involving FSI and material failure.
