Dassault Systèmes Simulia Corp. is a computer-aided engineering (CAE) vendor. Formerly known as Abaqus Inc. and previously Hibbitt, Karlsson & Sorensen, Inc., (HKS), the company was founded in 1978 by David Hibbitt, Bengt Karlsson and Paul Sorensen, and has its headquarters in Providence, Rhode Island.
In October 2005, Dassault Systèmes acquired Abaqus, Inc.{{Cite web |url=http://www.managingautomation.com/maonline/news/read/Dassault_Syst%C3%A8mes_Acquires_Realistic_Simulation_Software_Firm_6934 |title=Dassault Systèmes Acquires Realistic Simulation Software Firm - Managing Automation |access-date=2012-07-07 |archive-date=2013-01-28 |archive-url=https://archive.today/20130128084103/http://www.managingautomation.com/maonline/news/read/Dassault_Syst%C3%A8mes_Acquires_Realistic_Simulation_Software_Firm_6934 |url-status=dead }} and announced Simulia, the brand encompassing all DS simulation solutions, including Abaqus and Catia Analysis applications. Dassault Systèmes Simulia Corp. is the legal entity that encompasses the Simulia brand of Dassault Systèmes.
Abaqus product suite
{{main|Abaqus}}
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.{{cite web |url=http://www.3ds.com/products/simulia/portfolio/abaqus/abaqus-portfolio/abaquscfd/ |title=Abaqus/CFD - Dassault Systèmes |website=www.3ds.com |url-status=dead |archive-url=https://web.archive.org/web/20120716000919/http://www.3ds.com/products/simulia/portfolio/abaqus/abaqus-portfolio/abaquscfd/ |archive-date=2012-07-16}} Each of these packages offers additional, optional modules that address specialized capabilities required by some customers.
Abaqus/Standard provides analysis technology to solve traditional implicit finite element analysis, including static, dynamic, and thermal analyses, all powered with 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 support for pre- and post-processing provided in Abaqus/CAE. These simulation capabilities address a range of nonlinear coupled fluid-thermal and fluid-structural problems.

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.{{Cite web|url=http://www.3ds.com/products/simulia/portfolio/simulia-v5/overview/|title=SIMULIA V5 - Dassault Systèmes®}}

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.{{cite journal|url=https://aemjournal.org/index.php/AEM/article/view/407/pdf|title=A review on Computational Electromagnetics Methods|first1=P.|last1=Sumithra|first2=D.|last2=Thiripurasundari|date=1 March 2017|accessdate=19 October 2018|journal=Advanced Electromagnetics|volume=6|issue=1|doi=10.7716/aem.v6i1.407|doi-access=free}}{{cite book|title=Advanced FDTD Methods: Parallelization, Acceleration, and Engineering Applications|url=https://archive.org/details/advancedfdtdmeth00yuwe_643|url-access=limited|first=Wenhua|last=Yu|page=[https://archive.org/details/advancedfdtdmeth00yuwe_643/page/n11 1]|year=2011|publisher=Artech House|isbn=9781608071777|quote=A wide variety of packages are currently available, and some of the most popular EM software packages include [...] CST microwave studio that utilizes the finite integration technique (FIT).}}{{cite book|title=Computational Electromagnetics for RF and Microwave Engineering|first=David B.|last=Davidson|page=xv|year=2010|publisher=Cambridge University Press|isbn=9781139492812|quote=the three codes whose application is discussed in this book, viz.

As an electromagnetic design tool, CST Studio Suite is chiefly used in industries such as telecommunications, defense, automotive, aerospace, electronics and medical equipment.{{cite web |title=CST Simulations Benefit from Intel® Xeon Phi™ Coprocessors |url=https://www.intel.com/content/www/us/en/processors/xeon/cst-simulations-benefit-xeon-phi.html |accessdate=23 October 2018 |publisher=Intel |page=16}} One application of CST Studio Suite is the design and placement of antennas and other radio-frequency components.{{cite web|url=https://www.cst.com/solutions/markets/antennas|title=Antennas|accessdate=23 October 2018|publisher=CST}} The antenna systems on the BepiColombo Mercury Planetary Orbiter were developed using CST Studio Suite to investigate their radiation pattern and possible electromagnetic interference.{{cite web|url=https://www.cst.com/solutions/article/airbus-defence-and-space-uses-cst-studio-suite-to-analyze-antenna-systems-on-bepicolombo|title=Airbus Defence and Space Analyzes Antenna Systems on BepiColombo Using CST STUDIO SUITE |accessdate=23 October 2018|first1=Christian|last1=Imhof|author2=Airbus Defence and Space|author2-link=Airbus Defence and Space|website=CST}}
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.{{cite web|title=A marriage of design and EM simulation|first=Andy|last=Pye|publisher=Environmental Engineering|accessdate=23 October 2018|url=https://environmentalengineering.org.uk/news/a-marriage-of-design-and-em-simulation-4409/|date=2016-11-14}} 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.{{cite web |last=Johnston |first=Hamish |date=26 May 2009 |title=Electromagnetic software accelerates ahead |url=https://physicsworld.com/a/electromagnetic-software-accelerates-ahead/ |accessdate=23 October 2018 |publisher=Physics World}}
