Smooth Particle Hydrodynamics (SPH) is a technique used to analyze bodies that do not have high cohesive forces among themselves and undergo large deformation, such as liquids and gases. The SPH Generation option lets you perform SPH analysis on a component with volume, such as airbags or fuel tanks. To learn more about the concept of SPH Generation, see SPH Mesh in the HyperMesh User's Guide.
