Meshless Methods
This seminar will introduce attendees to the application of the meshless “Element-Free Galerkin” (EFG) and “Smooth Particle Hydrodynamics” (SPH) methods in LS-DYNA. The seminar will outline the theoretical bases and thoroughly refer to the settings required in the LS-DYNA input deck in order to carry out an EFG/SPH simulation. Examples will be used to get an even better understanding of how to use these methods.
The seminar is recommended for engineers already experienced in the use of LS-DYNA who intend to apply meshless methods.
