Smoothed Particle Hydrodynamics in LS-DYNA

Given by Dr Jean Luc Lacome

Duration: 2 Days

Objective

The objective of this course is to teach the engineer how to use the SPH option of LS-DYNA. Theory is presented to understand the basic principles of this meshfree method. Detailed descriptions of the data required to run LS-DYNA analysis are given. Examples are used to illustrate the points made in the lectures.

Who should attend?

This course is recommended for engineers experienced in LS-DYNA and finite elements and who want to use a meshfree method. SPH is a numerical method well suited for problems where large mesh distortions
occur and also for fluid/structure interaction problems.
