LS-DYNA delivers a diverse array of analyses with extremely fast and efficient parallelization.
Ansys LS-DYNA is the industry-leading explicit simulation software used for applications like drop tests, impact and penetration, smashes and crashes, occupant safety, and more.
Ansys LS-DYNA is the most used explicit simulation program in the world and is capable of simulating the response of materials to short periods of severe loading. Its many elements, contact formulations, material models and other controls can be used to simulate complex models with control over all the details of the problem. Ansys LS-DYNA applications include:

In addition to the features from 2024 R1, we are excited to announce the general availability of pyDYNA – a Pythonic interface for the powerful LS-DYNA solver.
A new eigenmode solver designed for large models with many modes computed offers more accuracy and faster performance compared to current approaches (8X faster for an electric car model).
With a new machine-learning-based method to accurately model fiber-reinforced plastic parts for crash and other simulations, these new features significantly improve modeling accuracy with support for strain rate-dependency, tension/compression asymmetric properties, and, importantly, including the residual stress and warpage from molding simulation results.
New features focus on accurate modeling for multiphysics and FSI applications. This includes adaptive ISPG support for fluid-structure coupling, moving porous regions to simplify the modeling of different regions in a complex heart valve replacement simulation, a new JETLEN feature that allows for more accurate modeling of airbags, and much more.
Using simulation, doctors can determine the magnitude and location of brain strains, enabling them to improve concussion treatment.
Clinicians are unclear about how to measure the damage incurred by head impacts. Concussions diagnosed by magnetic resonance images (MRIs), computed tomography (CT) scans and blood tests often deliver inconclusive results.
Dr. Michael Power leads clinical care at Beaumont Hospital in Dublin, Ireland, which specializes in the treatment of head injuries — many of which occur during contact sports. Several years ago, he aligned with CADFEM Ireland — Ansys’ channel partner in Ireland — on a mission that would combine engineering simulation with clinical expertise to research the mechanisms of concussion. They sought to understand whether simulation software could help define the causes of concussions, reduce their number and improve concussion treatment.
LS-DYNA CAPABILITIES
Engineers can tackle simulations involving material failure and look at how the failure progresses through a part or through a system. Models with large amounts of parts or surfaces interacting with each other are also easily handled, and the interactions and load passing between complex behaviors are modeled accurately. Using computers with higher numbers of CPU cores can drastically reduce solution times.
LS-DYNA elements, contact formulations, material models and other controls can be used to simulate complex models with control over all the details of the problem.
