Abaqus

Abaqus (derived from the mechanical calculating device abacus ) is a commercial program package, which can be problems of solid- statics and dynamics, heat transfer, electromagnetism and fluid dynamics to edit. Initially included only the Abaqus finite element program, and this is often meant even today, when there is talk of Abaqus. Today, the purchase or rental of the program a number of other packages may also be supplied to support the work. Abaqus / CAE, what is the abbreviation for Complete Abaqus Environment and complete Abaqus environment is, is an interactive program that serves the modeling and calculation and analysis of results. Today Abaqus is in the automotive, aerospace, shipbuilding and defense industries worldwide popular computer program. Because of its good reputation and diverse user interface 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 issued in 1978 by the firm HKS, which was founded by David Hibbit, Bengt Karlsson and E. Paul Sorensen and had its headquarters in Pawtucket / Rhode Iceland. 2002 HKS name into ABAQUS Inc. and in 2004 ended a strategic partnership with Dassault Systèmes, which then a year later, in 2005, ABAQUS, Inc. took over. The continuous growth of the company led ABAQUS Inc. in 2004 from the original building in Pawtucket, by Rising Sun Mills also move Rhode Iceland to Rhode Iceland. 2008 ABAQUS, Inc., Dassault Systèmes Simulia Corp. in. renamed. Through acquisitions and its own development, its product range is continually being expanded. Today Abaqus is one represented by several products that sells Simulia and in over 40 offices worldwide.

The representation in Europe was until 2006 ABAQUS Inc, today SIMULIA European Headquarters in Maastricht.

The German representation is based in Aachen today with a second office in Munich, originally Abacom Software GmbH, ABAQUS Germany GmbH, from 2005 to 2011 Dassault Systèmes Simulia GmbH.

Working with Abaqus

Special features of Abaqus are:

  • Abaqus is known for its performance in solving nonlinear problems but can also be used in linear problems.
  • Abaqus has a reputation as a high-quality program.
  • Possibility of parallel computing and thus short computation times.
  • There is an implicit and an explicit equation solvers who understand broadly the same input files and allow easy data exchange.
  • There is a product- own pre-and post-processor.
  • A Python interface allows scripted model - building, equation solving and automated post-processing.
  • Extensive ( English ) documentation.
  • " Readable " syntax that small manipulations on the entry enabled.

Problem competence

The particular strengths of Abaqus are in non-linear problems. Causes of these non-linearities can be:

  • Geometric nonlinearity: wrinkles, bumps, large rotations, membranes, deformation- dependent forces
  • Material nonlinearity: 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:

  • Heat conduction
  • Mechanics
  • Fluid Mechanics
  • Electromagnetism

For solutions in solid mechanics are different formulations before:

  • Statics
  • Modal analysis and modal dynamics
  • Implicit dynamics for linear and nonlinear problems
  • Explicit dynamics for highly nonlinear problems.
  • XFEM: crack propagation.
  • Gekopplete Euler - Lagrangian formulation, for example, sloshing of liquid in a container
  • SPH ( smoothed particle hydrodynamics ) for the most extreme deformations such as the impact of a projectile
  • Particle- based method for the discrete element method to simulate the motion of many particles, for example, when mixing of pills.

Modules

Originally Abaqus was a pure finite element program and even today it is the main component of the delivered scope. The program is divided into

  • Abaqus / Foundation: linear statics and dynamics, such as natural frequency and 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 soil or structures.
  • Abaqus / CFD: calculation of flows with heat transfer and fluid-structure coupling
  • Abaqus / Aqua: analysis, the loads due to Umströmungen include with water or air.
  • Abaqus / Design: Shows the influence that small changes of the model result.
  • Abaqus Topology Optimization ( ATOM ): Shape and topology optimization.
  • Abaqus fe-safe: post processor for fatigue calculation.

Additional tools:

  • CZone for Abaqus: considering the impact effect on composites in Abaqus / Explicit.
  • Abaqus Knee Simulator ( AKS ): Simulation of knee implants
  • Crash test dummy and barrier models: For Crash calculations

Are supplied as optional functionality

  • AMS (automatic multi-level substructuring ) eigenvalue solver
  • Multidisciplinary simulation with MpCCI interface

Available.

The two interactive programs are

  • Abaqus / CAE: modeling, calculation and analysis.
  • Abaqus / Viewer: Tool for evaluation, which is included in Abaqus / CAE is also sold separately.

Among the programs CATIA/V5 and V6, SolidWorks, Pro / ENGINEER, NX (Siemens) and Moldflow has Abaqus interfaces that facilitate data transfer.

System Requirements

Previously Abaqus could be operated inter alia on the operating systems Linux/x86-32, Windows/x86-32, HP-UX/Itanium, Linux / Itanium, and AIX / POWER. Due to the effort the program to adapt to these systems and increasing importance of Linux/x86-64 and Windows/x86-64 today supports only the latter two operating systems. The exact system requirements for Abaqus can be looked up on the internet.
