ANSYS AUTODYN is not a normal explicit Finite Element or Computational Fluid Dynamics code. From the very beginning we developed ANSYS AUTODYN to handle naturally and effectively the non-linear behavior of fluids and structures in an integrated fashion. Additional unique features that make ANSYS AUTODYN different from other explicit software:
Multiple & Coupled Solution Techniques
Multiple solution techniques (Lagrange, Multi-Material Euler, Euler-FCT, ALE, SPH, Shells, Beams) can be used in combination and fully coupled in a single problem to avail the user of the most appropriate and best suited method available.

Convenient, Practical and Sophisticated Modeling Features
Features such as natural fragmentation, remapping, restarting, de-zoning, part activation, and a fast 2D solution enable users to produce high resolution results efficiently.

Extensive Material Model Library
As Century Dynamics Ltd. is constantly striving to assure that analysis results are accurate as possible, one of our highest priorities is to provide material models and material data to achieve that goal. Therefore, AUTODYN features an extensive material model library combining thermodynamic and constitutive responses for many solids, liquids and gases (e.g., metals, composites, ceramics, glass, concrete, soil, explosives). A combination of virtually all equation of state, strength and failure/damage material models is possible and supported by virtually all solution techniques.
Intuitive Interactive Graphical User Interface
Problem setup, simulation and post-processing are all done through the same graphical user interface within the ANSYS Workbench Platform. It provides CAD geometry import, complex geometry generation and meshing capabilities. In addition, it provides wizards for ease of model set-up as well as data checking during model creation and on-line documentation. At all levels of interaction with the program context sensitive help is available to instantly assist the users with guidance and clarification on how to use the program and what values may need to be specified. In addition, input that must be entered by the user is significantly reduced by the programs use of safe default values for most data parameters and by automatic data generation.

Parallel Processing on Shared Memory and Distributed Memory Systems
To take advantage of the benefits of faster turn-around problems can be run on parallel computer systems, including shared memory and (distributed) clustered computer systems. Domain decomposition is used to produce the most efficient parallel solution.

Open Architecture
The majority of the capabilities, such as equation of state, strength model, failure/damage model, implemented within AUTODYN can be expanded by the user through the use of User Subroutines and User Variables. Templates for User Subroutines with full documentation of data available in the routine and data to be produced by the user are provided with the standard program, minimizing the effort for implementing new capabilities.

Extensively Validated Solution Techniques by
Experiments
The solution techniques used in AUTODYN have been repeatedly validated by comparing the results generated with experimental data. The Technical Library contains numerous comparisons by customers of experimental and simulated results.
