Abaqus FEA[4][5] (formerly ABAQUS) is a software suite for finite element analysis and computer-aided engineering, originally released in 1978. The name and logo of this software are based on the abacus calculation tool.[6] The Abaqus product suite consists of five core software products:[5]
- Abaqus/CAE, or "Complete Abaqus Environment" (a backronym with an obvious root in Computer-Aided Engineering[7]). It is a software application used for both the modeling and analysis of mechanical components and assemblies (pre-processing) and visualizing the finite element analysis result. A subset of Abaqus/CAE including only the post-processing module can be launched independently in the Abaqus/Viewer product.
- Abaqus/Standard, a general-purpose Finite-Element analyzer that employs implicit integration scheme (traditional).
- Abaqus/Explicit, a special-purpose Finite-Element analyzer that employs explicit integration scheme to solve highly nonlinear systems with many complex contacts under transient loads.
- Abaqus/CFD, a Computational Fluid Dynamics software application which provides advanced computational fluid dynamics capabilities with extensive support for preprocessing and postprocessing provided in Abaqus/CAE.[8]
- Abaqus/Electromagnetic, a Computational electromagnetics software application which solves advanced computational electromagnetic problems.
The Abaqus products use the open-source scripting language Python for scripting and customization. Abaqus/CAE uses the fox-toolkit for GUI development.
Applications
Abaqus is used in the automotive, aerospace, and industrial products industries. The product is popular with non-academic and research institutions in engineering due to the wide material modeling capability, and the program's ability to be customized. Abaqus also provides a good collection of multiphysics capabilities, such as coupled acoustic-structural, piezoelectric, and structural-pore capabilities, making it attractive for production-level simulations where multiple fields need to be coupled.
Abaqus was initially designed to address non-linear physical behavior; as a result, the package has an extensive range of material models such as elastomeric (rubberlike) material capabilities.

Every complete finite-element analysis consists of 3 separate stages:
- Pre-processing or modeling: This stage involves creating an input file which contains an engineer's design for a finite-element analyzer (also called "solver").
- Processing or finite element analysis: This stage produces an output visual file.
- Post-processing or generating report, image, animation, etc. from the output file: This stage is a visual rendering stage.
Abaqus/CAE is capable of pre-processing, post-processing, and monitoring the processing stage of the solver; however, the first stage can also be done by other compatible CAD software, or even a text editor. Abaqus/Standard, Abaqus/Explicit or Abaqus/CFD are capable of accomplishing the processing stage. Dassault Systemes also produces Abaqus for CATIA for adding advanced processing and post processing stages to a pre-processor like CATIA.
Solvers Comparison
The following is a comparison between the solver capabilities of Abaqus/Standard and Abaqus/Explicit.[9]
Feature | Common | ABAQUS/Standard only | ABAQUS/Explicit only |
---|---|---|---|
Element library | Comprehensive | no limits | only elements appropriate for explicit solutions |
Material models | Comprehensive | only yield models | yield and fracture models |
Solution methods | Implicit Integration needs solve multiple coupled equation Using the K Matrix (F=Ku) Stable |
explicit integration step by step using small time steps sometimes not stable | |
Required Disk Space | repetitive calculations likely takes a lot of space |
no repetitive calculation normal | |
Types of Problems | Linear: non-linear: Contact*: usual systems** |
Can solve Can solve Can solve if simple Optimal under steady*** loads |
Can solve Optimal. even if highly non-linear Optimal. even for complex and varying conditions Optimal under transient*** loads like Impact, Pulse and Explosion |
- Notes
^* The more complex the contacts become, the more repetitive calculations ABAQUS/Standard has to solve, and the more time and disk space needed; ABAQUS Explicit is the optimal choice in this case
^** Like static elements (see the picture,) dynamic elements, thermal elements and electrical elements
^ ^*** Steady, Static and Constant loads are the same. Transient loads include: quasi-static loads (slowly varying loads in which the effect of inertial is small enough to neglect) and dynamic loads (faster varying loads).
