SPH in Abaqus

SPH (Smoothed Particle Hydrodynamics) is a numerical method used in Abaqus for modeling fluid-structure interaction problems. It is a meshless approach that uses a set of particles to discretize the fluid domain, allowing for efficient and accurate simulation of complex flows. The method is particularly useful for problems with large deformations, fragmentation, and free surface effects. Abaqus' implementation of SPH includes a wide range of capabilities, such as adaptive smoothing lengths, particle splitting and merging, and boundary handling techniques. It can be used in combination with other Abaqus features, such as finite element analysis, to model coupled fluid-structure systems. You can learn how to use this method by practical examples in this package; some them are Projectile impact simulation on a cementitious material, TNT explosion simulation inside a rock with the SPH method, Bullet Movement through Water Pipe in Abaqus.
