## Chapter 1: 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 enabling the set up, running, and postprocessing of problems, 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.

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.
