Simulia (company)

The Abaqus suite consists of three core products: Abaqus/Standard, Abaqus/Explicit, and Abaqus/CAE (Complete Abaqus Environment). In addition, recent versions of Abaqus (6.10 onwards) include Abaqus/CFD for computational fluid dynamics simulations. Each of these packages offers additional, optional modules that address specialized capabilities required by some customers.

Abaqus/Standard provides analysis technology for traditional implicit finite element analysis, including static, dynamic, and thermal analyses, powered by a range of contact and nonlinear material options.

Abaqus/Explicit specializes in analysis technology tailored for transient dynamics and quasi-static analyses, employing explicit time integration methods. This approach proves suitable for various applications, including drop tests, crushing scenarios, and manufacturing processes.

Abaqus/CAE provides a complete modeling and visualization environment for Abaqus analysis products.

Abaqus/CFD provides advanced computational fluid dynamics capabilities, with pre- and post-processing support in Abaqus/CAE. These simulation capabilities address a range of nonlinear, coupled fluid-thermal and fluid-structural problems.

Simulia

In addition to developing the pre-existing Abaqus portfolio, DS has also developed the Simulia V5 and V6 product suites, which aim to combine modelling and simulation into a single tool.

CST Studio Suite is a computational electromagnetics tool developed by Dassault Systèmes Simulia. It contains several different simulation methods, including the finite integration technique (FIT), finite element method (FEM), transmission line matrix (TLM), multilevel fast multipole method (MLFMM) and particle-in-cell (PIC), as well as multiphysics solvers for other domains of physics with links to electromagnetics.

As an electromagnetic design tool, CST Studio Suite is chiefly used in industries such as telecommunications, defense, automotive, aerospace, electronics, and medical equipment. One application of CST Studio Suite is the design and placement of antennas and other radio-frequency components. The antenna systems on the BepiColombo Mercury Planetary Orbiter were developed using CST Studio Suite to investigate their radiation pattern and possible electromagnetic interference.

Electromagnetic compatibility (EMC), the analysis and mitigation of interference and electromagnetic environmental effects, is another application, because simulation allows potential issues to be identified earlier in the design process than physical testing alone can. Similarly, CST Studio Suite is also used to analyze signal integrity, the quality of electric signal transmission, on printed circuit boards and other electronics.

Other areas of research where CST Studio Suite has been applied include accelerator physics, biological electromagnetics, nanotechnology, and metamaterials.
