Starting with Abaqus V2 (in 1979), Abaqus/Aqua simulates hydrodynamic wave loading on flexible structures for offshore pipelines. Multiphysics technology has been a part of Abaqus from the beginning. 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. The Abaqus Unified FEA product suite has significant capabilities that are used to solve multiphysics problems. The flexibility provided by this integration allows Abaqus/Explicit to be applied to those portions of the analysis where high-speed, nonlinear, transient response dominates the solution while Abaqus/Standard can 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. Similarly, an analysis that starts in Abaqus/Standard can be continued in Abaqus/Explicit. The results at any point within an Abaqus/Explicit run can be used as the starting conditions for continuation in Abaqus/Standard. Abaqus/Explicit is supported within the Abaqus/CAE modeling environment for all common pre- and postprocessing needs. Abaqus/Explicit is designed for production environments, so ease of use, reliability, and efficiency are key ingredients in its architecture. The ability of Abaqus/Explicit to effectively handle severely nonlinear behavior such as contact 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. Abaqus/ExplicitĪbaqus/Explicit is a finite element analysis product that is particularly well-suited to simulate brief transient dynamic events such as consumer electronics drop testing, automotive crashworthiness, and ballistic impact. 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. Similarly, an analysis that starts in Abaqus/Explicit can be continued in Abaqus/Standard. The results at any point within an Abaqus/Standard run can be used as the starting conditions for continuation in Abaqus/Explicit. Abaqus/Standard is supported within the Abaqus/CAE modeling environment for all common pre- and postprocessing needs. 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. For example, one may start by performing a nonlinear engine cover mounting analysis including sophisticated gasket mechanics. Within a single simulation, it is possible to analyze a model both in the time and frequency domain.
Examples include sealing pressure in a gasket joint, steady-state rolling of a tire, or crack propagation in a composite airplane fuselage. Abaqus/StandardĪbaqus/Standard employs solution technology ideal for static and low-speed dynamic events where highly accurate stress solutions are critically important. Everything in CAE can be automated with Python which is a general purpose programming language with vast engineering and scientific libraries. With material test data automated routines can be used to fit material model coefficients to accurately model the materials. CAE has robust meshing tools to accommodate virtually any geometry including repair tools. It can also import from other FEA packages like Nastran and Ansys. There are also associative translators for many of the most popular CAD tools like Catia, SolidWorks and Pro/Engineer. It has the ability to import a variety of CAD geometries from many neutral formats. Abaqus/CAEĪbaqus/CAE simply put is the Graphical User Interface (GUI) for Abaqus. This alleviates or reduces the need for physical testing while providing a greater level of insight to the physics occurring in the design. What FEA provides is a way to simulate how a structure will respond to stimuli such as force, pressure or temperature. The collection of finite elements are referred to as a mesh. This is similar to how a picture is broken up into individual pixels. Complete solutions for realistic simulation.įinite Element Analysis (FEA) is a technique where geometry from Computer Aided Design (CAD) is discretized into finite elements.
