'''Ansys, Inc.''' is an American multinational company with its headquarters based in Canonsburg, Pennsylvania. It develops and markets CAE/multiphysics engineering simulation software for product design, testing and operation and offers its products and services to customers worldwide. On July 17, 2025, the company became a subsidiary of Synopsys.<ref>{{cite web | title=Synopsys acquires simulation specialist Ansys for $35 billion following Chinese regulator approval — Merger to power end-to-end design platform | date=17 July 2025 | url=https://www.tomshardware.com/tech-industry/semiconductors/synopsys-acquires-simulation-specialist-ansys-for-usd35-billion-following-chinese-regulator-approval-merger-to-power-end-to-end-design-platform }}</ref>
==History== ===Origins=== Ansys was founded in 1970 as Swanson Analysis Systems, Inc. (SASI) by John Swanson. The idea for Ansys was first conceived by Swanson while working at the Westinghouse Astronuclear Laboratory in the 1960s.<ref name="eight">{{cite news|title=Ansys opens new markets with user-friendly software|url=http://www.readingeagle.com/ap/article/ansys-opens-new-markets-with-user-friendly-software|publisher=Associated Press|access-date=June 10, 2017|date=May 16, 2017}}</ref> At the time, engineers performed finite element analysis (FEA) by hand.<ref name="eight" /> Westinghouse rejected Swanson's idea to automate FEA by developing general purpose engineering software, so Swanson left the company in 1969 to develop the software on his own.<ref name="eight" /> He founded SASI the next year, working out of his farmhouse in Pittsburgh.<ref name="five">{{cite book | last=Lee | first=H.-H. | title=Finite Element Simulations with Ansys Workbench 17 | publisher=SDC Publications | year=2017 | isbn=978-1-63057-088-0 | url=https://books.google.com/books?id=G4EEDgAAQBAJ&pg=PA50 | access-date=June 9, 2017 | page=50}}</ref><ref name="seven">{{cite news|title=Small firm big player in software industry|first=Mark|last=Houser|newspaper=Tribune|date=February 5, 1995}}</ref>
Swanson developed the initial ANSYS software on punch cards and used a mainframe computer that was rented by the hour.<ref name="eight"/> Westinghouse hired him as a consultant, under the condition that any code he developed for Westinghouse could also be included in the Ansys product line.<ref name="five"/> Westinghouse became the first Ansys user.<ref name="five"/>
Swanson sold his interest in the company to venture capitalists in 1994, and the company was renamed "Ansys" after the software. Ansys went public on NASDAQ in 1996. In the 2000s, the company acquired other engineering design companies, obtaining additional technology for fluid dynamics, electronics design, and physics analysis. Ansys became a component of the NASDAQ-100 index on December 23, 2019.<ref>{{cite news |last1=Tascarella |first1=Patty |title=Ansys becoming part of Nasdaq-100 Index |url=https://www.bizjournals.com/pittsburgh/news/2019/12/16/ansys-becoming-part-of-nasdaq-100-index.html |access-date=16 March 2023 |publisher=Pittsburgh Business Times |date=16 December 2019}}</ref>

Ansys went public in 1996, raising about $46 million in an initial public offering.<ref name="six" /> By 1997, Ansys had grown to $50.5 million in annual revenue.<ref name="four" /> In the late 1990s, Ansys shifted its business model<ref name="six">{{cite book|first=David|last=Weisberg|title=The Engineering Design Revolution|url=http://www.cadhistory.net/22%20Analysis.pdf|chapter=22|access-date=2017-12-05|archive-date=2021-02-03|archive-url=https://web.archive.org/web/20210203231846/http://www.cadhistory.net/22%20Analysis.pdf|url-status=dead}}</ref> away from software licenses, and corresponding revenue declined.<ref name="six" /> However, revenue from services increased.<ref name="six" /> From 1996 to 2000, profits at Ansys grew an average of 160% per year.<ref name="three" /> In February 2000, Jim Cashman was appointed CEO.<ref name="six"/>

In 1996, Ansys released the DesignSpace structural analysis software, the LS-DYNA crash and drop test simulation product, and the Ansys Computational Fluid Dynamics (CFD) simulator.<ref name="two"/> Ansys also added parallel processing support for PCs with multiple processors.<ref name="two"/> The educational product Ansys/ed was introduced in 1998.<ref name="five"/> Version 6.0 of the main Ansys product was released in December 2001.<ref name="five"/> Version 6.0 made large-scale modeling practical for the first time, but many users were frustrated by a new blue user interface.<ref name="five"/> The interface was redone a few months later in 6.1.<ref name="five"/> Version 8.0 introduced the Ansys multi-field solver, which allows users to simulate how multiple physics problems would interact with one another.<ref name="Engineers 2004">{{cite book | last=Engineers | first=American Institute of Chemical | title=Chemical Engineering Progress | publisher=American Institute of Chemical Engineers | issue=v. 100, nos. 1-12 | year=2004 | url=https://books.google.com/books?id=FbovAQAAIAAJ | access-date=June 15, 2017}}</ref>
Version 8.0 was published in 2005<ref name="two"/> and introduced Ansys' fluid–structure interaction software,<ref name="two"/> which simulates the effect structures and fluids have on one another.
