Ansys LS-Dyna

multiphysics solver For nonlinear, Dynamic, and Impact simulations

Ansys LS-Dyna is the industry-leading scalable multiphysics simulation software that is designed to simulate highly nonlinear dynamic short duration events. 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. It is used for applications like drop tests, impact and penetration, smashes and crashes, occupant safety and much more.

Ansys LS-Dyna boasts many benefits such as product safety, certification & compliance, faster time to market, improved performance, product optimization, and product reliability and protection. The LS-Dyna software is completely integrated with the Ansys enterprise suite of software tools providing predictive engineering for a wide range of applications. It is also the first commercial software that is available on the ARM architecture.

In addition, Ansys LS-Dyna is optimized for high-performance computing environments, making it capable of handling large and complex simulations efficiently. This capability is essential for tackling large-scale problems and detailed simulations.

Key Features

Ansys LS-Dyna element and contact formulations, material models and other controls can be used to simulate complex models with control over all the details of the problem.

Electromagnetics Solver

EM solves the Maxwell equations using FEM & BEM in the Eddy current approximation. This is suitable for cases where the propagation of electromagnetic waves in air (or vacuum) can be considered as instantaneous. The main applications are magnetic metal forming or welding, induced heating, and battery abuse simulation.

Mutiphysics Solver

Multiphysics Solver include ICFD for Incompressible Fluids, electromagnetic solver, EM for battery abuse, and CESE for compressible fluids.

Advanced CAE

Peridynamics & SPG: compelling method for brittle fracture analysis in isotropic materials as well as certain composites such as CFRP. Isogeometric Analysis (IGA): employs basis functions from computer-aided design (CAD) for numerical analysis.

Particle Methods

There are several particle methods using LS-Dyna. AIRBAG_PARTICLE is used for for airbag gas particles which models the gas as a set of rigid particles in random motion. PARTICLE_BLAST for high explosive particles which models high explosive gas and air modeled Particle gas.
