Abaqus/Explicit is an explicit-dynamic finite-element solver that is well-suited to simulate brief transient dynamic events such as consumer electronics drop tests, automotive crashes, and ballistic impacts. The ability of Abaqus/Explicit to effectively handle severely nonlinear behavior such as contact makes it very attractive for the simulation of many quasi-static events, such as rolling of hot metal and slow crushing of energy absorbing structures. Abaqus/Explicit is designed for production environments, so ease of use, reliability, and efficiency are key ingredients in its architecture. Abaqus/Explicit is supported within the Abaqus/CAE modeling environment for all common pre- and post-processing.
Abaqus/Explicit may be coupled with Abaqus/Standard. A simulation that starts in Abaqus/Standard can be continued in Abaqus/Explicit and vice versa. This import functionality allows Abaqus/Explicit to be applied to those portions of the analysis that are well-suited to an explicit-dynamic solution technique while Abaqus/Standard may be applied to those portions of the analysis more suitable for an implicit solver.

Multiphysics with Abaqus
The Abaqus product suite has significant capabilities that are used to solve multiphysics problems. Fully integrated as core Abaqus functionality these multiphysics capabilites have been applied extensively for many engineering applications on products and engineering projects.
From the same model, same element library, same material data, and same load history, an Abaqus structural FEA model can easily be extended to include additional physics interaction.
CZone for Abaqus
CZone can be used for advanced crush simulation of energy-absorbing structures made of laminated composites. CZone can be coupled with the extended Abaqus capabilities to analyse crashworthiness for the automotive and aerospace industry.
