EXHIBIT 99  Certain Factors Regarding Future Results

            Information provided by the Company or its spokespersons may from
            time to time contain forward-looking statements concerning projected
            financial performance, market and industry segment growth, product
            development and commercialization or other aspects of future
            operations.  Such statements will be based on the assumptions and
            expectations of the Company's management at the time such statements
            are made.  The Company cautions investors that its performance (and,
            therefore, any forward-looking statement) is subject to risks and
            uncertainties.  Various important factors, including, but not
            limited to the following, may cause the Company's future results to
            differ materially from those projected in any forward-looking
            statement.

            Potential Fluctuations in Operating Results.  The Company may
            experience significant fluctuations in future quarterly operating
            results.  Fluctuations may be caused by many factors, including the
            timing of new product releases or product enhancements by the
            Company or its competitors; the size and timing of individual
            orders, including a fluctuation in the demand for and the ability to
            complete large contracts; software errors or other product quality
            problems; competition and pricing; customer order deferrals in
            anticipation of new products or product enhancements; reduction in
            demand for the Company's products; changes in operating expenses;
            mix of software license and maintenance and service revenue;
            personnel changes; and general economic conditions.  A substantial
            portion of the Company's operating expenses is related to personnel,
            facilities and marketing programs.  The level of personnel and
            personnel expenses cannot be adjusted quickly and is based, in
            significant part, on the Company's expectation for future revenues.
            The Company does not typically experience significant order backlog.
            Further, the Company has often recognized a substantial portion of
            its revenue in the last month of a quarter, with this revenue
            frequently concentrated in the last weeks or days of a quarter, and
            increasingly is dependent upon receiving large orders of perpetual
            licenses involving the payment of a single up-front fee. The Company
            believes that large orders of this type may reflect an increasing
            demand for enterprise-wide software solutions from certain of the
            Company's customers, which, if continued, may increase the
            volatility of the Company's revenues and profit from period to
            period.  More recently, the Company has also experienced an increase
            in renewals and sales of noncancellable annual leases, for which a
            portion of the annual license fee is recognized as paid-up revenue
            upon renewal or inception of the lease.

            As a result, product revenues in any quarter are substantially
            dependent on orders booked and shipped in the latter part of that
            quarter, and revenues for any future quarter are not predictable
            with any significant degree of accuracy.


                                                                               1

 
            Stock Market Volatility.  Market prices for securities of software
            companies have generally been volatile.  In particular, the market
            price of the Company's common stock has been and may continue to be
            subject to significant fluctuations as a result of factors affecting
            the Company and software industry or securities markets in general.

            In addition, a large percentage of the Company's common stock is
            held by TA Associates, Inc. and various institutional investors.
            Consequently, actions with respect to the Company's common stock by
            either TA Associates, Inc. or certain of these institutional
            investors could have a significant impact on the market price for
            the stock.

            Rapidly Changing Technology; New Products; Risk of Product Defects.
            The markets for the Company's products are generally characterized
            by rapidly changing technology and frequent new product
            introductions that can render existing products obsolete or
            unmarketable. A major factor in the Company's future success will be
            its ability to anticipate technological changes and to develop and
            introduce in a timely manner enhancements to its existing products
            and new products to meet those changes. If the Company is unable to
            introduce new products and respond to industry changes on a timely
            basis, its business, financial condition and results of operations
            could be materially adversely affected. The introduction and
            marketing of new or enhanced products require the Company to manage
            the transition from existing products in order to minimize
            disruption in customer purchasing patterns. There can be no
            assurance that the Company will be successful in developing and
            marketing, on a timely basis, new products or product enhancements,
            that its new products will adequately address the changing needs of
            the marketplace, or that it will successfully manage the transition
            from existing products. Software products as complex as those
            offered by the Company may contain undetected errors or failures
            when first introduced or as new versions are released, and the
            likelihood of errors is increased as a result of the Company's
            commitment to accelerating the frequency of its product releases.
            There can be no assurance that errors will not be found in new or
            enhanced products after commencement of commercial shipments. Any of
            these problems may result in the loss of or delay in market
            acceptance, diversion of development resources, damage to the
            Company's reputation, or increased service or warranty costs, any of
            which could have a materially adverse effect upon the Company's
            business, financial condition and results of operations.

            Dependence on Distributors.  The  Company distributes its products
            principally through its global network of 35 independent, regional
            ANSYS Support Distributors ("ASDs").  The ASDs sell ANSYS

                                                                               2

 
            and DesignSpace(R) products to new and existing customers, expand
            installations within their existing customer base, offer consulting
            services and provide the first line of ANSYS technical support.  The
            ASDs have more immediate contact with most customers who use ANSYS
            software than does the Company.  Consequently, the Company is highly
            dependent on the efforts of the ASDs.  Difficulties in ongoing
            relationships with ASDs, such as delays in collecting accounts
            receivable, ASDs' failure to meet performance criteria or to promote
            the Company's products as aggressively as the Company expects, and
            differences in the handling of customer relationships, could
            adversely affect the Company's performance.  Additionally, the loss
            of any major ASD for any reason, including an ASD's decision to sell
            competing products, could have a materially adverse effect on the
            Company.  Moreover, the Company's future success will depend
            substantially on the ability and willingness of its ASDs to continue
            to dedicate the resources necessary to promote the Company's
            products and to support a larger installed base of the Company's
            products. If the ASDs are unable or unwilling to do so, the Company
            may be unable to sustain revenue growth.

            Competition.  The CAD, computer-aided engineering ("CAE") and
            computer-aided manufacturing ("CAM") markets are intensely
            competitive.  In the traditional CAE market, the Company's primary
            competitors include MacNeal-Schwendler Corporation, Hibbitt,
            Karlsson and Sorenson, Inc. and MARC Analysis Research Corporation.
            The Company also faces competition from smaller vendors of
            specialized analysis applications in fields such as computational
            fluid dynamics.  In addition, certain integrated CAD suppliers such
            as Parametric Technology Corporation and Structural Dynamics
            Research Corporation provide varying levels of design analysis and
            optimization and verification capabilities as part of their product
            offerings. The entrance of new competitors would likely intensify
            competition in all or a portion of the overall CAD, CAE and CAM
            market. Some of the Company's current and possible future
            competitors have greater financial, technical, marketing and other
            resources than the Company, and some have well established
            relationships with current and potential customers of the Company.
            It is also possible that alliances among competitors may emerge and
            rapidly acquire significant market share or that competition will
            increase as a result of software industry consolidation. Increased
            competition may result in price reductions, reduced profitability
            and loss of market share, any of which would materially adversely
            affect the Company's business, financial condition and results of
            operations.

            Dependence on Senior Management and Key Technical Personnel.  The
            Company is highly dependent upon the ability and experience of its
            senior executives and

                                                                               3

 
            its key technical and other management employees. Although the
            Company has entered into employment agreements with two executives,
            the loss of these, or any of the Company's other key employees,
            could adversely affect the Company's ability to conduct its
            operations.

            Risks Associated with International Activities.  A significant and
            growing portion of the Company's business comes from outside the
            United States. Risks inherent in the Company's international
            business activities include imposition of government controls,
            export license requirements, restrictions on the export of critical
            technology, political and economic instability, trade restrictions,
            changes in tariffs and taxes, difficulties in staffing and managing
            international operations, longer accounts receivable payment cycles
            and the burdens of complying with a wide variety of foreign laws and
            regulations.  Effective patent, copyright and trade secret
            protection may not be available in every foreign country in which
            the Company sells its products.  The Company's business, financial
            condition and results of operations could be materially adversely
            affected by any of these risks.

            Additionally, countries in the Asia Pacific region, including Japan,
            have recently experienced weaknesses in their currency, banking and
            equity markets.  These weaknesses could adversely affect consumer
            demand for the Company's products and ultimately the Company's
            financial position or results of operations.

            Dependence on Proprietary Technology.  The Company's success is
            highly dependent upon its proprietary technology.  The Company does
            not have patents on any of its technology and relies on contracts
            and the laws of copyright and trade secrets to protect its
            technology.  Although the Company maintains a trade secrets program,
            enters into confidentiality agreements with its employees and
            distributors and limits access to and distribution of its software,
            documentation and other proprietary information, there can be no
            assurance that the steps taken by the Company to protect its
            proprietary technology will be adequate to prevent misappropriation
            of its technology by third parties, or that third parties will not
            be able to develop similar technology independently. Although the
            Company is not aware that any of its technology infringes upon the
            rights of third parties, there can be no assurance that other
            parties will not assert technology infringement claims against the
            Company, or that, if asserted, such claims will not prevail.

            Increased Reliance on Perpetual Licenses and Noncancellable Annual
            Leases. The Company has historically maintained stable recurring
            revenue from the sale of monthly lease licenses for its software
            products.  While the Company has experienced an increase in customer
            preference for

                                                                               4

 
            perpetual licenses that involve payment of a single up-front fee and
            that are more typical in the computer software industry, most
            recently, it has also experienced an increase in customer preference
            for noncancellable annual leases. Although lease license revenue
            currently represents a significant portion of the Company's software
            license fee revenue, to the extent that perpetual license and
            noncancellable annual lease license revenue increase as a percent of
            total software license fee revenue, the Company's revenue in any
            period will increasingly depend on sales completed during that
            period.

            Year 2000 Computer Systems Compliance. The Company has established a
            corporate-wide Year 2000 task force, led by the Company's Vice
            President of Corporate Quality, with the representation of all major
            business segments. This task force is responsible for identifying,
            evaluating and overseeing the implementation of necessary changes to
            computer systems and applications to achieve a Year 2000 date
            conversion with no effect on customers or disruption of business
            operations. The task force is currently in the process of assessing
            its exposure to contingencies related to the Year 2000 Issue for
            previous releases of its products. The Company plans to utilize both
            internal and external resources to reprogram, or replace and test
            the software for Year 2000 modifications. The Company plans to
            substantially complete the Year 2000 project no later than December
            31, 1998. The total remaining cost of the Year 2000 project will be
            funded through operating cash flows. The Company does not expect the
            amounts required to be expensed to have a material effect on its
            financial position or results of operations. During 1997 and the
            first six months of 1998, the costs related to the assessment of,
            and preliminary efforts in connection with, its Year 2000 project
            and the development of its action plan were not material.

            The Company is also communicating with its significant suppliers and
            customers to identify critical related issues which need to be
            resolved. The Company's total Year 2000 project costs and estimates
            to complete include the estimated costs and time associated with the
            impact of a third party's Year 2000 issue, and are based on
            presently available information. However, there can be no guarantee
            that the systems of other companies on which the Company's systems
            rely will be converted on a timely basis, or that a failure to
            convert by another company, or a conversion that is incompatible
            with the Company's systems, would not have a material adverse effect
            on the Company.

            The costs of the project and the date on which the Company plans to
            complete the year 2000 action plan are based upon management's best
            estimates, which are derived utilizing numerous assumptions of
            future events including the availability of certain resources, third
            party modification plans and

                                                                               5

 
            other factors. However, there can be no guarantee that these
            estimates will be achieved and actual results could differ
            materially from those plans. Specific factors that might cause such
            material differences include, but are not limited to, the
            availability and cost of personnel with necessary expertise in this
            area, the ability to identify and correct all relevant computer
            codes and similar uncertainties.

                                                                               6
