Smoothed Particle Hydrodynamics

Due to the true meshless nature of SPH, the method is perfectly suitable in situations with very large deformations. Typical applications of SPH in LS-DYNA include impact simulations of fluids or solids or other scenarios where it is essential to capture the momentum exchange accurately. Attendees will learn the application of the SPH with the aid of many workshop examples.

The course instructor Prof. Mhamed Soul of the University of Lille is a long-term software developer at LSTC and is frequently implementing new features for the methods ALE and SPH in LS-DYNA. This seminar aims at engineers who have already worked with LS-DYNA and would like to use SPH as a meshless method.
