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:

July 2024
The 2024 R2 release of Ansys LS-DYNA enables customers to increase efficiency throughout the full workflow for complex multiphysics simulations.
All sections of an LS-DYNA input file can now be easily split and saved into separate sub-input files for use inside and outside of Mechanical. Simplifying the process of modifying or extracting specific sections, such as a mesh, deformed geometry, or named selections, for reuse in subsequent simulations.
Major enhancements to streamline NVH workflows with complex geometries using Boundary Element Method (BEM) acoustic analyses. These include a dedicated BEM acoustics meshing workflow to significantly reduce total meshing time and the integration of the BEM acoustics solver, which can evaluate high frequencies and large frequency ranges without the need to mesh the fluid volume.
Enhancements to multiphysics coupling enable increased accuracy when simulating the impact of structural and thermal induced deformations on electromagnetic components. Applications include battery modeling, electromagnetic forming, induction hardening, and 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.
