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. For example, one may start by performing a nonlinear engine cover mounting analysis including sophisticated gasket mechanics. Following the mounting analysis, the pre-stressed natural frequencies of the cover can be extracted, or the frequency domain mechanical and acoustic response of the pre-stressed cover to engine induced vibrations can be examined. Abaqus/Standard is supported within the Abaqus/CAE modeling environment for all common pre- and postprocessing needs.
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. The flexibility provided by this integration allows Abaqus/Standard to be applied to those portions of the analysis that are well-suited to an implicit solution technique, such as static, low-speed dynamic, or steady-state transport analyses; while Abaqus/Explicit may be applied to those portions of the analysis where high-speed, nonlinear, transient response dominates the solution.
This optional add-on analysis capability for Abaqus/Standard allows the user to select the automatic multi-level substructuring (AMS) eigensolver when performing a natural frequency extraction. The Abaqus/AMS eigensolver offers significant performance advantages over the default Lanczos method, particularly when a large number of eigenmodes is required for a system with many degrees of freedom. Benchmark tests indicate that natural frequency extraction problems can be solved anywhere between 10 times and 25 times faster with the new AMS eigensolver, depending on the complexity of the model.
Abaqus/Aqua is an add-on product for use in offshore engineering applications. It includes features for jacket and riser analysis, J-tube pull simulations, bottom-bending calculations, and floating structure studies. Structures can be subjected to drag, buoyancy, and fluid inertia loading because of steady current and wave effects. Wind loading is available for structures that rise above the free surface of the water.
Abaqus/Design is an add-on product that complements Abaqus/Standard for use in design sensitivity analysis (DSA). Design sensitivities are useful for understanding the behavior of a design and for predicting the effect of design changes. The design sensitivities can be used to provide the foundation for "instant re-analysis" or "what-if " design studies and for gradient-based, optimal design.
Abaqus/Foundation provides access to the static and dynamic analysis linear perturbation functionality of Abaqus/Standard. When Abaqus/Foundation is available, the solution process automatically detects problems that can be solved using linear perturbation procedures and uses Abaqus/Foundation instead of Abaqus/Standard to manage your license token pool efficiently.
