Check out the key features of Ansys LS-DYNA
Implicit and Explicit Solvers
Ansys LS-DYNA software seamlessly transitions between Implicit and Explicit solvers for diverse simulations. Engineers can optimize analyses, choosing the most suitable solver for specific scenarios—be it structural dynamics, crash simulations, or other complex applications. Ansys LS-DYNA ensures flexibility, performance, and accuracy.
Frequency Domain Analysis
Frequency domain analysis in LS-Dyna enables users to delve into features like acoustic BEM and FEM, and fatigue SSD, frequency response, random vibration, response function, spectrum analysis, steady-state dynamics. These capabilities find applications in NVH, acoustic analysis, defense, earthquake engineering, and fatigue analysis.
ICFD for Incompressible Fluid
The ICFD solver functions as an independent CFD code featuring steady-state and transient solvers, turbulence models for RANS/LES, handling free surface flows, and both isotropic and anisotropic porous media flow. It's capable of coupling with structural, EM, and thermal solvers.
Electromagnetics Solver
EM module utilizes Boundary Element Method (BEM) and Finite Element Method (FEM) to solve Maxwell's equations within the Eddy current approximation. It's ideal for cases where the rapid propagation of electromagnetic waves in air (or vacuum) is applicable. Applications include magnetic metal forming or welding, induced heating, and battery abuse simulation.
Multiphysics Solver
Ansys LS-DYNA's Multiphysics Solver is a comprehensive suite featuring ICFD for Incompressible Fluids, an electromagnetic solver optimized for battery abuse scenarios, and CESE tailored for compressible fluids. This solution addresses a wide range of complex simulation scenarios, ensuring accuracy and efficiency across diverse physics domains.
Particle Methods
Ansys LS-DYNA provides versatile particle methods for diverse applications. AIRBAG_PARTICLE simulates airbag gas particles, PARTICLE_BLAST models explosive scenarios, and the Discrete Element Method spans agriculture, food handling, chemical and civil engineering, mining, and mineral processing.
Contact – Linear and Nonlinear
Contacts are established by specifying locations (parts, sets) to check for potential penetration between nodes and segments. Penetration searches, using various algorithms, occur regularly. In penalty-based contacts, forces resist and resolve penetrations. For realistic force distribution, ensure refined mesh for both rigid and deformable bodies.
Dummy models (ATD)
Dummies (ATDs) predict human injury during impacts by mimicking human behavior.
Barriers like Offset Deformable Barrier (ODB) and Movable Deformable Barrier (MDB) models from LSTC correlate with proprietary customer tests.
Tires models developed by FCA are downloadable and use 2D CAD data, incorporating specific material modeling for elastomers and plies.
Meshless – SPH
The SPH method within Ansys LS-DYNA® is integrated with finite and discrete element methods, broadening its applicability to diverse and intricate issues, encompassing multiphysics interactions such as explosion or fluid-structure interaction.
Meshless – ALE
Ansys LS-DYNA features mesh-free particle solvers: smooth particle hydrodynamics (SPH) and discrete methods like DEM, PBM, and CPM. Widely used in scenarios like hypervelocity impacts, explosions, welding, and fracture analysis in various materials, these solvers excel in diverse applications.
Adcanced CAE
Peridynamics & SPG provide innovative material failure simulation—SPG for ductile and Peridynamics for brittle materials. Both use a stable bond-based failure mechanism, eliminating the need for erosion techniques.
Isogeometric Analysis (IGA) utilizes CAD-based functions for precise analysis, preserving true geometry instead of approximation.
Supporting Tools
Ansys LS-OPT integrates with LS-DYNA for efficient design optimization and probabilistic analysis, addressing conflicting objectives. LS-TaSC™ collaborates seamlessly with LS-DYNA for effective optimization, system identification, and probabilistic analysis in large nonlinear problems, including dynamic loads and contact conditions.
