Abaqus product suite

The Abaqus suite consists of three core products - Abaqus/Standard, Abaqus/Explicit and Abaqus/CAE (Complete Abaqus Environment). In addition to this, recent versions of Abaqus (6.10 onwards) also contain Abaqus/CFD for computational fluid dynamic simulations. Each of these packages offers additional, optional modules that address specialized capabilities required by some customers. Abaqus/Standard provides Abaqus analysis technology to solve traditional implicit

material options. Abaqus/Standard also has optional add-on and interface products that address design sensitivity analysis, offshore engineering, and integration with third-party software, e.g. plastic injection molding analysis. Abaqus/Explicit provides analysis technology focused on transient dynamics and quasi-static analyses using an explicit time integration, which is appropriate in many applications, such as drop tests, crushing, and manufacturing processes. Abaqus/CAE provides a complete modeling and visualization environment for Abaqus analysis products. With direct access to CAD models, advanced meshing and visualization, and with an exclusive view towards Abaqus analysis products, Abaqus/CAE is the modeling environment of choice for many Abaqus users. Abaqus/CFD provides advanced computational fluid dynamics capabilities with extensive support for pre- and postprocessing provided in Abaqus/CAE. These scalable parallel CFD simulation capabilities address a broad range of nonlinear coupled fluid-thermal and fluid-structural problems.


Simulia

In addition to the development of the pre-existing Abaqus portfolio, DS has also developed Simulia V5 and V6 product suites which seeks to combine the modelling and simulations aspect into one tool.
