       ANSYS Delivers Another Quarter of Solid Revenue and Strong Earnings

    SOUTHPOINTE, Pa., Nov. 5 /PRNewswire-FirstCall/ -- ANSYS, Inc. (Nasdaq:
ANSS), a global innovator of simulation software and technologies designed to
optimize product development processes, today announced third quarter 2003
results. ANSYS' third quarter and year-to-date GAAP results include:

     - Total revenue of $28.0 million, as compared to $21.7 million in the
       third quarter of 2002; total revenue of $80.3 million in the first nine
       months of 2003 as compared to $65.7 million for the nine months ended
       September 30, 2002;

     - Diluted earnings per share of $0.33 as compared to $0.26 for the third
       quarter of 2002; diluted earnings per share of $0.89 through
       September 30, 2003 as compared to $0.81 for the first nine months of
       2002; and

     - Cash flows from operations of $7.1 million in the third quarter of 2003
       and $28.7 million in the first nine months of 2003.

    Excluding the adverse impact on reported software license revenue of
purchase accounting adjustments related to the Company's February 2003
acquisition of CFX and acquisition-related amortization (see discussion below),
ANSYS' third quarter and year-to-date adjusted (non-GAAP) results include:

     - Total adjusted revenue of $28.9 million, as compared to $21.7 million
       in the third quarter of 2002; total adjusted revenue of $82.7 million
       in the first nine months of 2003 as compared to $65.7 million for the
       nine months ended September 30, 2002;

     - An overall adjusted operating profit margin, excluding total
       amortization, of 34% as compared to 29% for the third quarter of 2002;
       and an overall adjusted operating profit margin, excluding total
       amortization, of 31% as compared to  30% for the first nine months of
       2002; and

     - Adjusted diluted earnings per share of $0.41 as compared to $0.28 for
       the third quarter of 2002; adjusted diluted earnings per share of $1.10
       compared to $0.86 for the nine month period ended September 30, 2002.

    ANSYS President and CEO, Jim Cashman, commenting on the current quarter's
solid business performance, said, "The third quarter was a very positive quarter
for us on a number of important initiatives. We continued to make tremendous
strides in integrating our recently acquired CFX product line, which contributed
to our ability to post record third quarter revenue and earnings results.
Additionally, we made important progress in advancing our leadership in
technology, which we believe has been a key driver to both the continued
penetration into our extensive installed base, as well as our ability to expand
into new markets."

    Cashman added, "While we continue to focus on improving our sales
productivity and execution in certain geographic regions, we believe that our
financial results, coupled with our technology and market leadership, provide us
with a strong platform from which we can continue to grow our business."

    The adjusted results highlighted above represent non-GAAP (Generally
Accepted Accounting Principles) financial measures. A reconciliation of these
measures to the appropriate GAAP measures is included in the condensed financial
statements included in this release.

    Adjustments to Reported GAAP Financial Results

    - Purchase Accounting Adjustment for Acquired Deferred Revenue:

    As announced February 26, 2003, ANSYS acquired CFX for approximately $22
million in cash. In accordance with the fair value provisions of EITF 01-3
"Accounting in a Business Combination for Deferred Revenue of an Acquiree,"
acquired deferred software license revenue of approximately $4.8 million was
recorded on the opening balance sheet, which was approximately $3.4 million
lower than the historical carrying value. Although this purchase accounting
requirement has no impact on the Company's business or cash flow, it adversely
impacts the Company's reported GAAP software license revenue for the first
twelve months post-acquisition. In order to provide investors with financial
information that facilitates comparison of both historical and future results,
the Company has and will continue to provide adjusted financial information,
which excludes the impact of the purchase accounting adjustment, through this
twelve-month period.

    - Acquisition Related Amortization:

    As previously discussed, the Company completed its recent acquisition of CFX
in February 2003. Prior to that, the Company also acquired CADOE S.A. and ICEM
CFD Engineering in November 2001 and August 2000, respectively. These
acquisitions have all been accounted for as purchases, resulting in the
recording of a significant amount of goodwill and identifiable intangible
assets. As a result of the amortization associated with intangible assets
related to these acquisitions, ANSYS' quarterly and year-to-date financial
results are not comparable with prior periods.

    To enable investors and other interested parties to compare 2003 financial
results to historical and future periods, ANSYS is providing its 2003 third
quarter and year-to-date reported GAAP results as well as financial results that
have been adjusted for the impact of the items described above.

    Third Quarter 2003 and Nine Months Ended September 30, 2003 Reported GAAP
Results

    ANSYS reported net income for the third quarter of $5.4 million, or $0.33
diluted earnings per share, based on 16.2 million weighted average shares
outstanding. For the quarter ended September 30, 2002, ANSYS reported net income
of $4.1 million, or $0.26 diluted earnings per share, based on 15.5 million
weighted average shares outstanding. For the nine months ended September 30,
2003, ANSYS reported net income of $14.1 million, or diluted earnings per share
of $0.89, based on 15.8 million weighted average shares outstanding. For the
nine months ended September 30, 2002, ANSYS reported net income of $12.7
million, or diluted earnings per share of $0.81, based on 15.7 million weighted
average shares outstanding. Cash and short-term investments at September 30,
2003 totaled $72.3 million and ANSYS remains debt free.

    Innovative Products Launched

    ANSYS continued its tradition of introducing innovative technologies
designed to meet the ever-expanding needs of its customers and the diverse
markets that it serves. The ability to model and simulate multiphysics-based
systems and their manufacturing and operating conditions in the same familiar
and unified graphical user interface has significant value to our customers in
terms of simulation accuracy and reliability, time to market, cost, quality and
innovations. These current product releases are highlighted by:

    Continued Technological Leadership:

     - Seamless integration of ANSYS multiphysics capabilities and CFX CFD
       technologies allows, for the first time, customers' multiple
       disciplinary development teams to collaborate and work together. This
       unique attribute will benefit customers from various complex product
       industries including aerospace, automotive, power generation and
       electronics.

     - ANSYS' new Multi-field solver is a true advance in open systems
       simulation.  This powerful solver allows customers to utilize
       engineering experts throughout their company, and even within their
       supply chains, each simulating their own design issues, to combine the
       results and gain a complete understanding of the overall system
       effects.

     - High performance solution algorithms allow complex simulation of
       complete products and systems to be performed in minutes and hours
       rather than days.

     - Component mode synthesis technology allows larger sized products
       (such as planes and ships) to be divided into smaller and manageable
       pieces that can be modeled and simulated independently by many
       engineering groups on small to medium sized computers.  This technology
       also enables the combining of the behavior of these smaller pieces to
       yield the whole system response.

    Leveraging Legacy Data to Spur Product Innovation:

     - Legacy technologies such as FE Modeler and Interface for NASTRAN
       allow customers to easily migrate to ANSYS solutions while protecting
       their investment in legacy product data, knowledge and intellectual
       property.

     - Parametric modeling technology (ANSYS ParaMesh) allows legacy data to
       be immediately utilized in rapid "what-if" simulations with full
       parametric optimizations, without recreating CAD geometry, and allows
       engineers to quickly optimize designs based upon product performance
       requirements.

    ANSYS will hold a conference call at 10:30 A.M. Eastern Time on November 5,
2003 to discuss third quarter results as well as to provide guidance regarding
fourth quarter business prospects. The dial in number is 800-857-7001 and the
passcode is "ANSYS". A replay will be available until November 7, 2003 by
dialing 800-756-9736. The conference call will be webcast live and can be
accessed, along with other financial information, on ANSYS' website, located at
www.ansys.com/newsrooms/investor.htm .
