Application Overview

ANSYS AUTODYN is an explicit analysis tool for modeling nonlinear dynamics of solids, fluids, gas, and their

interaction. With a fully integrated, easy to use graphical interface allowing set up, running, and post pro-

cessing of problems, 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.

ANSYS AUTODYN has been used in a vast array of projects and nonlinear phenomena. Here is a sample of

real projects where it has been used:

• Optimization and design of armor and anti-armor systems.

• Designing mine protection schemes for personnel carriers.

• Building protection measures and insurance risk assessment for blast effects in city centers.

• Aircraft impact risk assessment for power stations.

• Performance studies of oil-well perforating charges.

• Decommissioning of offshore platforms.

• Designing the shielding system on the International Space Station.

• Safety assessment of particle accelerators.

• Characterization of materials subjected to high dynamic loading.

• Drop test of electronics devices.

• Nuclear reactor safety.

• Nuclear waste transportation safety.

ANSYS AUTODYN Approach

Accessing ANSYS AUTODYN

The ANSYS AUTODYN application is available in the Component Systems section of the Workbench Toolbox.

Use this application to access the full functionality of the ANSYS AUTODYN product. Please refer to the online

ANSYS Workbench documentation for an explanation of the AUTODYN system components and supported

operations.

The structural FE components of the ANSYS AUTODYN solver can also be accessed using the Mechanical

Explicit Dynamics (AUTODYN) system located in the Analysis Systems section of the Workbench Toolbox.

Please refer to the Mechanical Help system for further details.

Steps to Using ANSYS AUTODYN

There are three different approaches to using ANSYS AUTODYN within ANSYS Workbench:

• Insert an Explicit Dynamics (AUTODYN) system from the Analysis Systems Toolbox. Use the Engineering

Data, Geometry, Model and Setup cells to define the structural/mechanical model. Drag and drop an

AUTODYN component system onto the Setup cell of the Explicit Dynamics (AUTODYN) system. Double

clicking the AUTODYN system Setup cell will start ANSYS AUTODYN and transfer the FE model definition

(including materials, mesh, connections, loading, constraints, analysis settings) from the Explicit Dynamics

(AUTODYN) system.

– Can only set-up models for the FE solvers (including connections and contact)

– 4-noded Tetrahedral meshes, 8-Noded Hexahedral Meshes, 4-and 3-noded Quad meshes, 2-noded

Beam meshes

– Try ANSYS AUTODYN Walkthrough Using Explicit Dynamics (p. 4) for more details of the procedure.

• Insert a Mesh system from the Component Systems Toolbox. Use the Geometry and Mesh cells to define

the structural/mechanical mesh. Drag and drop an AUTODYN component system onto the Mesh cell of

the Mesh system. Double clicking the AUTODYN system Setup cell will start ANSYS AUTODYN and

transfer the FE model definition (including mesh and named selections) from the Mesh system to the

AUTODYN system.

– Can only set-up meshes for the FE solvers

– 4-noded Tetrahedral meshes, 8-Noded Hexahedral Meshes, 4-and 3-noded Quad meshes, 2-noded

Beam meshes

– Try ANSYS AUTODYN Walkthrough Using Meshing (p. 10) for more details of the procedure.

• For simple geometries, integrated geometry creation, and meshing tools within ANSYS AUTODYN may

be used. Insert an AUTODYN Component System and double click the Setup cell to run and AUTODYN

application standalone.

– Can set up models for all solvers.



ANSYS AUTODYN Walkthrough Using Explicit Dynamics

1. Start Workbench.

2. Insert an Explicit Dynamics (AUTODYN) system from the Analysis Systems toolbox.

3. Right Click the Geometry cell (A3), and select Import a Geometry.

4. Double Click the Model cell (A4), to open up the Mechanical editor.

• Define the Body Interactions.



• Define the Mesh.




• Define Initial Conditions.



• Define Boundary Conditions.




• Define Analysis Settings.



5. Go to the Project Schematic, drag an AUTODYN Component System onto cell A5, to generate the link

between the Setup cell (A5) of the Explicit Dynamics system and the Setup cell (B2) of the AUTODYN

Component System.

6. Transfer the Explicit Dynamics Setup to AUTODYN.

• RMB on Expicit Dynamics (AUTODYN system Setup cell (A5), Select Update.




• The model definition in the Expicit Dynamics system will be transferred into the ANSYS AUTODYN

application.

Double click the Setup cell (B2) of the AUTODYN system to open the ANSYS AUTODYN application.

ANSYS AUTODYN Walkthrough Using Meshing

1. Start ANSYS Workbench.

2. Insert Meshing system from the Component Systems toolbox.



3. Right Click the Geometry cell (A2), Import a Geometry.

4. Double Click the Mesh cell (A3), to open up the meshing editor.

5. Define the Mesh.




6. Go to the Project Schematic, drag an AUTODYN Component System onto cell A3, to generate the

link between the Mesh cell (A3) of the Meshing system and the Setup cell (B2) of the AUTODYN

Component System.






7. Double click the Setup cell (B2) of the AUTODYN system to open the ANSYS AUTODYN application.

• The model definition in the Mesh system will be transferred into the ANSYS AUTODYN application

Mesh Named Selections.

• Complete the model setup in ANSYS AUTODYN.

• Execute the Simulation.

• Post-process results.



Note

Unlike release 11.0, changes to material assignment, loads and initial conditions made in AUTODYN

will be lost after an update of geometry or mesh. It is recommended that you link the AUTODYN

system to an Explicit Dynamics system rather than to a Meshing system. Materials, loads, and so

on may then be applied in the Explicit Dynamics system and will be retained after a geometry

or mesh update.





ANSYS AUTODYN On-line Help

Further information can be found in the comprehensive ANSYS AUTODYN On-line Help. This may be opened

by selecting Help, Contents from the ANSYS AUTODYN application menu bar, or by selecting the context-

sensitive Help buttons, situated throughout the ANSYS AUTODYN graphical user interface.
