ANSYS AUTODYN

ANSYS AUTODYN is a uniquely versatile explicit analysis tool for modeling the nonlinear dynamics of solids, fluids, gas and their interaction. Our focus is on providing the most advanced capability in the form of a very robust tool, is further enhanced by our focus on productivity. Users of ANSYS AUTODYN are able to complete simulation projects with significantly less effort, less time and lower total cost. The high productivity is a result of the easy to use, quick to learn intuitive, interactive graphical interface implemented in ANSYS AUTODYN. Additional time and effort savers in problem set-up and analysis are provided by automatic options to define contact, coupling interfaces and minimizing input requirements with the use of safe logical defaults.

Additionally with the graphical user interface in the ANSYS Workbench platform, ANSYS AUTODYN offers:

Finite element solvers for computational structural dynamics (FE)
Finite volume solvers for fast transient Computational Fluid Dynamics (CFD)
Mesh free particle solvers for high velocities, large deformation and fragmentation (SPH)
Multi-solver coupling for multi-physics solutions including coupling between FE, CFD and SPH
A wide suite of material models incorporating constitutive response and coupled thermodynamics
Serial and parallel computation on shared and distributed memory systems
Access to powerful geometry and meshing tools standard available through the ANSYS Workbench platform
Bi-directional connectivity to parametric ANSYS DesignModeler and CAD models

Comprehensive set of solution techniques, enabling users to select the most appropriate and accurate solver type possible for a wide range of problems

Open Architecture
Features can easily be extended by the user through the use of user subroutines and user variables

Extensive Material Model Library
The ANSYS AUTODYN material library is extensive and broad, with elastic, viscoelastic, strain hardening, porous compaction etc. strength models as well as linear, ideal gas, multiphase, explosive, crack softening etc. failure models

Parallel Processing on Shared Memory and Distributed Memory Systems
To reduce solution time, problems can be run on parallel computer systems, including shared memory and clustered computer systems

Convenient, Practical and Sophisticated Modeling Features
Two dimensional models, three dimensional models, remapping from 1-D to 2-D and from 2-D to 3-D, cell dezoning, part activation and deactivation, solver type remapping (i.e. Lagrangian to Eularian) and natural fragmentation are all powerfully accessible

Extensively Validated Solution Techniques by Experiments
Extensive commercial and military physical testing has been used for more than 20 years to correlate simulation model results with the complex physical realities experienced in high speed, high deformation short duration events
