Complete solutions for realistic simulation
Product simulation is often performed today by engineering groups using niche simulation tools from different vendors to simulate various design attributes. The use of multiple vendor software products creates inefficiencies and increases costs. SIMULIA delivers a scalable suite of unified analysis products that allow all users, regardless of their simulation expertise or domain focus, to collaborate and seamlessly share simulation data and approved methods without loss of information fidelity.
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. For example, in the automotive industry engineering work groups can 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.
- Accurate prediction of real-world product behavior enables companies to increase product reliability and reduce warranty costs.
- Significant reduction of the need for costly physical testing.
- Fast turnaround time enables simulation to influence decisions early in the product design process and eliminate costly re-designs.
- Increase engineering productivity through standardization on a single complete capability for structural simulation.
- Wide range of non-linear analysis procedures including structural stress, explicit dynamics, thermal stress, heat transfer, pore fluid diffusion, and more.
- Modern linear dynamics framework that includes high performance eigensolvers, transient and steady-state dynamics, random response, and substructures.
- Advanced material modeling capabilities encompassing metals, polymers, composites, concrete, and fracture mechanics.
- Robust general contact capability for modeling complex interactions between large assemblies of parts.
- High-performance solvers that minimize simulation turnaround time.
- You can now use the cyclic symmetry analysis technique in Abaqus/Explicit to reduce simulation time and memory requirement.
- Abaqus/Standard now enables running multiple nonlinear load cases from within a single job. This new capability significantly reduces run time and the number of output files compared to running multiple jobs.
- The import capability has been extended to allow transfer of nodal temperatures and user-defined field variables between Abaqus/Standard and Abaqus/Explicit.
- The extended finite element method (XFEM) now supports procedures with temperature degrees-of-freedom.
- Implicit dynamic analysis in Abaqus/Standard now supports adjoint sensitivities with respect to topology, shell thickness, and lattice sizing design variables.
- The LaRC05 damage initiation criteria for fiber-reinforced composites is now available in Abaqus/Standard and the Hosford-Coulomb damage initiation criteria for ductile metals is now available in both Abaqus/Standard and Abaqus/Explicit.
- The Valanis-Landel hyperelastic material model to analyze rubber-like materials is now available in Abaqus/Standard.
- Band-limited damping in Abaqus/Explicit allows you to apply a desired uniform damping ratio over a specified frequency range.
- Distortion control is now available for the C3D10 element in Abaqus/Explicit.
- New 3-DOF warping elements extend the meshed cross-section generation capability for composite beams such as those found in wind turbine rotor blades.
- The beam general section capability in Abaqus/Standard and Abaqus/Explicit now supports channel and hat-shaped cross sections.
- You can now use distributions to specify layer thicknesses for composite solid elements and use wedge (triangular prism) elements with a composite solid section definition.
- The “master” and “slave” terminology in Abaqus is being replaced with “main” and “secondary”.
- Several enhancements are introduced to improve performance and memory consumption for dynamic feature edge criteria in Abaqus/Explicit.
- Abaqus/CAE now provides a tool remove selected data from an odb which can significantly reduce file size.
- CATIA V5 geometry can now be directly imported on the Linux platform.
- SolidWorks assemblies can now be imported as multiple parts.
- User control over shear flow visualization has been improved.
- Abaqus/CAE now supports small-sliding general contact in Abaqus/Standard
- Abaqus/CAE now supports analytical fields when defining composite ply thickness distributions.
- You can now execute Abaqus/Explicit in hybrid mode using a combination of MPI and threads with each MPI process launching a user-specified number of threads. Hybrid execution takes advantage of the Non-Uniform Memory Access (NUMA) architecture and the trend of increasing the number of cores available on each socket.
- The iterative linear equation solver in Abaqus/Standard now supports common modeling features including hybrid elements, connector elements, distributing couplings, and hard contact.
- GPU acceleration of the AMS eigensolver is now supported on the Windows platform.
- Parallel scaling of linear static simulations with a large number of load cases has been significantly improved.
