The conversion technique of generating particles per parent element is intended to be used when the original finite element mesh deformations are significant and elements may distort. These two conversion techniques make use to turn Lagrangian elements to SPH particles. Particles can be generated per parent element, or particles can be generated based on a uniform background grid. It can be used in combination with other Abaqus features, such as finite element analysis, to model coupled fluid-structure systems. Abaqus’ implementation of SPH includes a wide range of capabilities, such as adaptive smoothing lengths, particle splitting and merging, and boundary handling techniques. ![]() The method is particularly useful for problems with large deformations, fragmentation, and free surface effects. 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. ![]() SPH (Smoothed Particle Hydrodynamics) is a numerical method used in Abaqus for modeling fluid-structure interaction problems.
