Introduction: general

This guide describes the theories used in Abaqus.

The Abaqus finite element system includes:

  • Abaqus/Standard, a general-purpose finite element program

  • Abaqus/Explicit, an explicit dynamics finite element program

Several add-on options that are available only if your license includes them can be used to further extend the capabilities of Abaqus/Standard and Abaqus/Explicit.

  • The Abaqus/Aqua option works with Abaqus/Standard and Abaqus/Explicit. Abaqus/Aqua contains optional features that are specifically designed for the analysis of beam-like structures installed underwater and subject to loading by water currents and wave action.

  • The Abaqus/Design option enables you to perform design sensitivity analysis (DSA). The Abaqus/Design option works with Abaqus/Standard.

  • Abaqus/AMS is an optional eigensolver that works within Abaqus/Standard providing very fast solution of large symmetric eigenvalue problems.

  • The Abaqus co-simulation technique provides two applications, available as separate add-on capabilities, for coupling between Abaqus and third-party analysis programs.

  • Abaqus/Foundation is an optional subset of Abaqus/Standard that provides more cost-efficient access to the linear static and dynamic analysis functionality in Abaqus/Standard.
