SPH

The examples in this section are from the SPH (Smooth Particle Hydrodynamics) class of LSTC. You may access the examples separately by the menu on the left. The examples are prepared for LS-DYNA 970 and upwards.

This example shows the deformation of two equivalent bars made of plastic material. Initial conditions are specified by *INITIAL_VELOCITY keyword. The upper bar is calculated using Lagrangian discretization, the lower one is calculated using SPH method.  …more

This example shows the impact of two equivalent bars made of plastic material against a planar rigid wall. The upper bar is calculated using Lagrangian discretization, the lower one is calculated using SPH method.  …more

This models the impact of two equivalent bars against a shell structure. The left bar is discretized using Lagrangian solid elements, the right one is discretized using SPH method.  …more

This is a model of a Taylor bar impacting a rigid wall. The bar is discretized using SPH method. Compare ALE course for solution of the Problem with Lagrangian and Eulerian methods.  …more
