Recent Developments in LS-DYNA
In this presentation Dr. John O. Hallquist, founder and president of Livermore Software Technology Corporation (LSTC), will give an overview about recent developments in LS-DYNA. LS-DYNA is a highly advanced general-purpose nonlinear finite element program that is capable of simulating complex real world problems. The distributed memory solver provides very short turnaround times on Unix, Linux and Windows clusters. The major development goal of LSTC is to provide within LS-DYNA capabilities to seamlessly solve problems that require • "MULTI-PHYSICS", • "MULTIPLE STAGES", • "MULTI-PROCESSING". Its fully automated contact analysis capabilities and error-checking features have enabled users worldwide to solve successfully many complex crash and forming problems. LSTC develops sophisticated tools for modeling and simulating the large deformation behavior of structures. In addition to LS-DYNA the tools LS-PREPOST for pre - and post-processing, and LS-OPT for optimization are developed by LSTC. The main applications are: • Large Deformation Dynamics and complex Contact Simulations • Crashworthiness Simulation • Occupant Safety Systems • Metal Forming • Explicit/ Implicit Analysis • Metal, Glass, and Plastics Forming • Multi-physics Coupling • Failure Analysis • Sophisticated Material Models • Fluid-Structure Interaction • SPH (Smooth Particle Hydrodynamics) • EFG (Element Free Galerkin) LSTC was founded in 1987 by John O. Hallquist to commercialize as LS-DYNA the public domain code that originated as DYNA3D. DYNA3D was developed at the Lawrence Livermore National Laboratory, by LSTC’s founder, John O. Hallquist.
