Dassault Systèmes Simulia Corp. is a company specializing in computer-aided engineering (CAE), previously known as Abaqus Inc. and Hibbitt, Karlsson & Sorensen, Inc. (HKS). Established in 1978 by David Hibbitt, Bengt Karlsson, and Paul Sorensen, the company’s main office is located in Providence, Rhode Island.
In October 2005, Dassault Systèmes acquired Abaqus, Inc., subsequently introducing Simulia as the umbrella brand for all DS simulation products, including Abaqus and Catia Analysis. The legal entity representing the Simulia brand is Dassault Systèmes Simulia Corp.
Abaqus product suite
The Abaqus portfolio comprises three principal products: Abaqus/Standard, Abaqus/Explicit, and Abaqus/CAE (Complete Abaqus Environment). Beginning with version 6.10, Abaqus/CFD was added to support computational fluid dynamics. Optional extensions are available to enhance specific functionalities.
Abaqus/Standard provides implicit finite element analysis capabilities suited for static, dynamic, and thermal challenges while supporting sophisticated contact algorithms and nonlinear material behavior.
Abaqus/Explicit specializes in transient dynamic and quasi-static simulations through explicit time integration methods, making it suitable for applications such as impact testing, crushing scenarios, and manufacturing process simulations.
Abaqus/CAE offers an all-encompassing environment for modeling and visualization that facilitates the setup of all types of Abaqus analyses.
Abaqus/CFD delivers state-of-the-art computational fluid dynamics tools integrated within Abaqus/CAE’s pre- and post-processing framework to address complex nonlinear fluid-thermal and fluid-structure interaction problems.
Simulia
Beyond the Abaqus range, Dassault Systèmes has developed the Simulia V5 and V6 suites to provide a cohesive platform that merges modeling with simulation capabilities.
CST Studio Suite
CST Studio Suite, created by Dassault Systèmes Simulia, is a computational electromagnetics software package incorporating various simulation techniques such as the finite integration technique (FIT), finite element method (FEM), transmission line matrix (TLM), multilevel fast multipole method (MLFMM), and particle-in-cell (PIC). The suite also offers multiphysics solvers interconnected with electromagnetic simulations.
This electromagnetic design software supports sectors including telecommunications, defense, automotive, aerospace, electronics, and medical devices. It is extensively utilized for antenna design and radio-frequency component placement. For instance, CST was employed to develop the antenna systems on the BepiColombo Mercury Planetary Orbiter by analyzing electromagnetic interference and radiation characteristics.
Additionally, CST Studio Suite plays a key role in electromagnetic compatibility (EMC) assessments to detect interference issues early during development phases and is used for signal integrity evaluations on printed circuit boards and electronic hardware.
Research applications extend to fields such as accelerator physics, bioelectromagnetics, nanotechnology, and metamaterials.
