Abaqus Unified FEA: Complete Solution for Realistic Simulation

Abaqus Overview
The Abaqus Unified FEA product suite offers powerful and complete solutions for both routine and sophisticated engineering problems covering a vast spectrum of industrial applications. Engineering work groups are able to consider full vehicle loads, dynamic vibration, multibody systems, impact/crash, nonlinear static, thermal coupling, and acoustic-structural coupling using a common model data structure and integrated solver technology. Best-in-class companies are taking advantage of Abaqus Unified FEA to consolidate their processes and tools, reduce costs and inefficiencies, and gain a competitive advantage.
Quickly and efficiently create, edit, monitor, diagnose, and visualize advanced Abaqus analyses. The intuitive interface integrates modeling, analysis, job management, and results visualization in a consistent, easy-to-use environment that is simple to learn for new users, yet highly productive for experienced users. Abaqus/CAE supports familiar concepts such as feature-based, parametric modeling, interactive/scripted operation, and GUI customization.

Users can create geometry, import CAD models for meshing, or integrate geometry-based meshes that do not have associated CAD geometry. Associative Interfaces for CATIA V5, SolidWorks, NX and Pro/ENGINEER enable synchronization of CAD and CAE assemblies and rapid model updates with no loss of user-defined analysis features.

Abaqus CAE
Abaqus/Standard employs solution technology ideal for static and low-speed dynamic events where highly accurate stress solutions are critically important. Examples include sealing pressure in a gasket joint, steady-state rolling of a tire, or crack propagation in a composite airplane fuselage. Within a single simulation, it is possible to analyze a model both in the time and frequency domain.

The results at any point within an Abaqus/Standard run can be used as the starting conditions for continuation in Abaqus/Explicit. Similarly, an analysis that starts in Abaqus/Explicit can be continued in Abaqus/Standard.

Abaqus/Explicit is particularly well-suited to simulate brief transient dynamic events such as consumer electronics drop testing, automotive crashworthiness, and ballistic impact. The ability of Abaqus/Explicit to effectively handle severely nonlinear behavior makes it very attractive for the simulation of many quasi-static events, such as rolling of hot metal and slow crushing of energy absorbing devices.

The results at any point within an Abaqus/Explicit run can be used as the starting conditions for continuation in Abaqus/Standard. Similarly, an analysis that starts in Abaqus/Standard can be continued in Abaqus/Explicit.

Design Simulation
Abaqus/CFD provides advanced computational fluid dynamics capabilities with extensive support for preprocessing and post-processing provided in Abaqus/CAE. These scalable parallel CFD simulation capabilities address a broad range of nonlinear coupled fluid-thermal and fluid-structural problems. Abaqus/CFD can solve the following types of incompressible flow problems:

Laminar and turbulent, internal or external, steady-state or transient flows,
Problems involving heat transfer and require an energy equation and that may involve buoyancy-driven flows,
Deforming-mesh analyses using an arbitrary Lagrangian Eulerian (ALE) description of the equations of motion, heat transfer, and turbulent transport.

Abaqus Multiphysics
The Abaqus Unified FEA product suite has significant capabilities that are used to solve multiphysics problems. These capabilities, developed over many years and fully integrated as core Abaqus functionality, have been used extensively for many engineering applications on products and engineering projects in use today. Multiphysics technology has been a part of Abaqus from the beginning. Starting with Abaqus V2 (in 1979), Abaqus/Aqua simulates hydrodynamic wave loading on flexible structures for offshore pipelines. Through the years additional multiphysics capabilities have been added, such as fluid, thermal, and electrical couplings, to name a few.

The advantage of Abaqus Multiphysics is the ease with which Multiphysics problems can be solved by the Abaqus structural FEA user. 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. No additional tools, interfaces, or simulation methodology are needed.

The following Multiphysics capabilities are available in Abaqus:
  • Coupled Eulerian-Lagrangian
  • Hydrostatic-Fluid-Mechanical
  • Piezoelectric-Mechanical
  • Structural-Acoustic
  • Thermal-Electric
  • Thermal-Mechanical
  • Thermal-Fluid-Mechanical
  • Structural-Pore Pressure
