| Abaqus overview | |
Abaqus FEA (derived from the mechanical computing device Abakus ) is a commercial program package with which problems of solid statics and dynamics, heat conduction, electromagnetism and fluid dynamics can be processed. Initially, Abaqus only contained the finite element program and this is often still meant today when Abaqus is mentioned. Today, when you buy or rent the program, a whole range of other packages are included to support the work. Abaqus / CAE, which is the abbreviation for Complete Abaqus Environment and means complete Abaqus environment , is an interactive program that is used to create and calculate models as well as to evaluate results. Today Abaqus is a computer program used worldwide in the automotive, aerospace, shipbuilding and defense industries. Because of its good reputation and the diverse user interfaces, Abaqus is also used in research (Fraunhofer institutes and universities). For the latter, there are special research and teaching licenses and student versions.
history
Abaqus was published for the first time in 1978 by the company HKS, which was founded by David Hibbitt, Bengt Karlsson and E. Paul Sorensen and was based in Pawtucket / Rhode Island. In 2002, HKS changed its name to ABAQUS Inc. and entered into a strategic partnership with Dassault Systèmes in 2004 , which ABAQUS Inc. took over a year later in 2005. The continuous growth of the company prompted ABAQUS Inc. to move from the original building in Pawtucket , Rhode Island to Rising Sun Mills on Rhode Island in 2004 . In 2008 ABAQUS Inc. became Dassault Systèmes Simulia Corp. renamed. The product range is continuously expanded through acquisitions and our own development. Today Abaqus is one of several products that Simulia sells and is represented in over 40 offices worldwide.
The agency in Europe was ABAQUS Europe BV, today SIMULIA European Headquarters in Maastricht , until 2006 .
The German agency is based in Aachen with a second branch in Munich, originally Abacom Software GmbH, ABAQUS Deutschland GmbH, from 2005 to 2011 Dassault Systèmes Simulia GmbH.
Working with Abaqus
Special properties of Abaqus are:
- Abaqus is known for its performance in solving non-linear problems, but can also be used in linear questions.
- Possibility of parallel computing and thus short computing times (iterative and direct linear equation solvers)
- There are implicit and one explicit time discretization schemes that understand largely the same input files and allow simple data exchange.
- There is a product's own pre- and post-processor.
- A Python interface allows script-controlled model construction, equation solving and automated post-processing.
- Documentation (in English) in html and pdf format.
- "Readable" syntax that allows small manipulations in the input
application areas
Abaqus can be used in linear and non-linear initial boundary value problems . Causes of non-linearities can be:
- Geometric non-linearity : buckling , bulging , large rotations, membranes, deformation-dependent forces
- Material non-linearity : plasticity , rubber elasticity , delamination , crack formation and propagation , seals
- Contact : crash test , press fits , deep drawing , friction
Abaqus can be used in the following physical disciplines:
Various formulations are available for solutions in solid mechanics :
- Statics
- Modal analysis and modal dynamics
- implicit dynamics for linear and non-linear questions
- explicit dynamics for highly non-linear questions.
- XFEM: crack propagation.
- Coupled Euler-Lagrange formulation e.g. B. for sloshing liquids in a container
- SPH (smoothed particle hydrodynamics) for extreme deformations such as the impact of a projectile
- Discrete element method for simulating the movement of many particles, e.g. B. when mixing pills.
Modules
Abaqus was originally a pure finite element program and this is still the main component of the scope delivered today. The program is divided into
- Abaqus / Foundation: linear statics and dynamics, e.g. B. Natural frequency or modal analysis .
- Abaqus / Standard: Linear and non-linear implicit analysis of statics and dynamics , heat conduction , electrical or electromagnetic reactions.
- Abaqus / Explicit: explicit dynamics of floors or constructions.
- Abaqus / CFD: Calculation of flows with heat transport and fluid-structure coupling
- Abaqus / Aqua: Analyzes that include loads due to water or air flowing around them.
- Abaqus / Design: Shows the influence that small changes to the model have.
Additional tools:
- CZone for Abaqus: Consideration of the impact effect on composite materials in Abaqus / Explicit.
- Abaqus Knee Simulator (AKS): Simulation of knee implants
- Crash test dummy and barrier models: For crash calculations
As an optional functionality
- AMS ( automatic multi-level substructuring ) eigenvalue solver
- Multidisciplinary simulation with the MpCCI interface
- CAD associative interfaces between Abaqus / CAE and CATIA / V5 and V6, SolidWorks , Pro / ENGINEER, which allows bidirectional data exchange,
available.
The two interactive programs are
- Abaqus / CAE: Model creation, calculation and evaluation.
- Abaqus / Viewer: Tool for evaluation that is contained in Abaqus / CAE, but is also sold separately from it.
Extensive English-language documentation in html and pdf format is supplied with these modules .
Abaqus has interfaces for the programs CATIA / V5 and V6, SolidWorks , Pro / ENGINEER, NX , Moldflow and MD ADAMS , which facilitate data transfer.

System requirements
In the past, Abaqus et al. a. be operated on the operating systems Linux / x86-32, Windows / x86-32, HP-UX / Itanium, Linux / Itanium and AIX / POWER. Because of the effort to adapt the program to these systems and the increasing importance of Linux / x86-64 and Windows / x86-64, only the latter two operating systems are supported today. The exact system requirements of Abaqus up to version 6.12 can be looked up on the Internet.
