Modeling
Abaqus offers a hybrid modeling approach that enables users to work with geometry-based data alongside imported meshes without associated geometry. It also provides a powerful modeling and visualization environment focused on complete support of Abaqus solver technology, customization capabilities, proven capture and reuse of analysis workflows, and the flexibility to implement user-defined subroutines. Feature-based, parametric modeling also makes Abaqus/CAE a highly efficient and effective pre- and postprocessor for every analysis need. Abaqus/CAE enables users to leverage the complete range of Abaqus analysis functionality, such as acoustics, connectors, damage, fracture, and failure. Familiar Abaqus concepts such as steps, interactions, sections, and materials make the user interface highly intuitive.
Geometry
Parts and assemblies can be created using the constraint-driven sketcher or imported from CAD systems. In addition, CAD associative interfaces for CATIA V6, CATIA V5, SolidWorks, and Pro/ENGINEER allow the synchronization and rapid analysis iterations of CAD and CAE assemblies.
Meshing
Abaqus/CAE offers a comprehensive meshing environment and provides a variety of sophisticated approaches for simplifying and speeding up mesh creation. Contact Abaqus provides comprehensive contact modeling capabilities, including the ability to model interactions between deformable bodies, rigid bodies, and self-contact. Abaqus automatically detects contact between different bodies, dramatically reducing missed contact definitions and the time required to define contact in complex assemblies.
Specialized Techniques
The direct cyclic procedure provides a computationally efficient way to analyze steady-state response to cyclic loading, which is useful in applications where thermal fatigue is of concern, such as in electronics or powertrain.
Adaptive remeshing in Abaqus alleviates uncertainty in mesh creation by automatically remeshing only where necessary to ensure accuracy.
The hydrostatic fluid cavity capability provides a simplified means to predict the mechanical response of structures, such as pressure vessels, hydraulically-driven mechanisms, or tires.
Advanced Materials
Increasing regulations, environmental concerns, and the need for lighter, more efficient products are forcing designers to seek out new materials such as lead-free solder, composites, and polymers. The Abaqus product suite provides an extensive library of material models that can be used to simulate the realistic behavior of biological tissue and traditional engineering materials, such as metals and rubber.
Advanced Analysis
Linear & Nonlinear
The implicit solution technology in Abaqus is ideal for solving static and low-speed dynamic events, such as sealing pressure in a gasket joint or crack propagation in a composite airplane fuselage. In addition to providing basic and advanced linear analysis capabilities, Abaqus also supports the general application of linear analysis techniques in cases where the linear response can depend on prior nonlinear load history, such as vibration of rotating machinery or the response of building structures due to earthquake loading. The explicit solution technology employed by Abaqus is well-suited for high-speed dynamic events, such as consumer electronics drop testing, automotive crashworthiness, and ballistic impact.
Multiphysics
Many industrial applications today involve the interaction of multiple physical phenomena. For example, to design safe and effective drug-eluting stents, engineers must account for the interplay between blood flow and stent deformation.
To address these applications, Abaqus provides robust multiphysics capabilities, including thermal-stress, thermal-electrical, low-frequency electromagnetics, structural acoustics, and fluid flow through porous media.
The Computational Fluid Dynamics (CFD) capability in Abaqus provides technology for simulating incompressible fluid flow, including turbulence and deforming meshes, such as the cooling of an automotive exhaust manifold or blood flow through an artery.
Abaqus also supports coupling of independent and external CFD software to perform Fluid-Structure Interaction (FSI) analysis, including smoothed particle hydrodynamics and Coupled Eulerian-Lagrangian (CEL).
Robustness and accuracy, combined with ease-of-use and high-performance computing, make Abaqus indispensable for simulating material and product behavior under real-world operating conditions.
High-Performance Computing
Reducing analysis turnaround time enables the examination of multiple and more detailed design scenarios. The distributed memory parallel direct solver technology in Abaqus sets a new benchmark for the industry, demonstrating impressive scaling and robustness. The parallel implementation of explicit dynamics in Abaqus, based on domain decomposition technology, greatly accelerates the solution process and boosts productivity.
Visualization
The comprehensive set of best-in-class visualization capabilities in Abaqus helps users interpret and communicate model data and analysis results. Visual diagnostics enable the progress of analyses to be tracked and assessed easily. Very large, complex models can be visualized using a wide range of options, including contour, path, X–Y, and ply stack plots. In addition, results in specific regions can be evaluated using display groups, view cuts, and free-body display.
