Simulation of short-duration dynamics and highly nonlinear problems with LS-DYNA

Using the explicit time integration method within LS-DYNA, very fast and highly dynamic problems can be effectively simulated. The Ansys LS-DYNA user interface makes input selections by means of proven and robust default solver and model settings. This means that even users with less simulation experience can use LS-DYNA very efficiently.

LS-DYNA integrated into Ansys Workbench

Simulation of arbitrary, nonlinear processes with very large deformations

Ansys LS-DYNA solves tasks with complex nonlinearities and avoids convergence issues. For example, short-duration dynamic applications, such as drop, impact and crash simulations, can be performed, e.g. nonlinear processes with large deformations, stability problems and complex contact problems.

Product Highlights
  • Proven, robust and reliable default solver settings
  • Seamless integration of LS-DYNA into Ansys Workbench
  • Parameterized CAD geometry modeling up to post-processing
  • LS-DYNA is the most commonly used explicit solver, making it practically the industry standard
  • Optimized for maximum computing power; shortest response times

This software is part of the Ansys structural mechanics product family

LS-DYNA is available as an integrated solution in Ansys Workbench as well as standalone as LST LS-DYNA. LST LS-DYNA is used for particularly complex tasks such as vehicle crashes.

Key facts and use cases of Ansys LS-Dyna

Oven drop test

Simulation-based product and packaging design. Numerical simulation of a drop test considerably cut experimental costs and enabled minimization of the unit casing’s plate thickness.

Containment test

Short-duration dynamic effects: centrifuge rotating at high speed. Transient simulation of centrifuge material failure.

Avalanche safety protection net

Combination of extremely soft and rigid structures. Highly nonlinear behavior of an avalanche safety protection net.

Safe kids’ furniture

Biomechanical strain when falling onto furniture edges. A simulation model can be used to quickly simulate, automatically evaluate and compare different ways in which a child might fall.
