In the threedimensional fluid-structure interaction simulation performed by the Lagrangian (meshfree) particle methods, the fluid particles' collisions treatment against solid boundaries using a realistic reflective physical approach, replacing artificial computational techniques (which use fictitious particles and unnatural repulsive forces) is an advance in the treatment of the contours, in the continuum domain. The benchmark study of a three-dimensional dam-breaking flow over a dry bed generating a wave that impacts a tall structure–a rigid obstacle fixed inside the reservoir–using the Smoothed Particle Hydrodynamics Method coupled with the reflective boundary conditions is presented in this paper. The findings showed good agreement with the previous literature data, proving the applicability of the reflective technique in the simulation of fluid-structure interaction problems in three-dimensional domains.
