Limit Boundary is available for an Explicit Dynamics analysis only. It is not available for LS-DYNA.
The Limit Boundary can only be scoped to bodies with the Reference Frame option set to Particle. It is used to impose limits on the position of SPH nodes in the X, Y, and Z directions. The limits effectively specify a rigid wall upon which SPH nodes encroaching on the limit will bounce off. For instance, specifying a minimum limit of -10 m in the X-direction is like specifying a rigid wall in the Y-Z plane positioned at X = -10 m.
