EXHIBIT 99.1

                  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; changes in
                  the 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 related expenses cannot be adjusted
                  quickly and is based, in significant part, on the Company's
                  expectation for future revenue. 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. During
                  certain quarterly periods, the Company has been dependent upon
                  receiving large orders of perpetual licenses involving the
                  payment of a single up-front fee and, more recently, has
                  shifted the business emphasis of its products to provide a
                  collaborative solution to the Company's customers. This
                  emphasis has increased the Company's average order size and
                  increased the related sales cycle time for the larger orders
                  and may have the effect of increasing the volatility of the
                  Company's revenue and profit from period to period. As a
                  result, product revenue in any quarter is

                                                                              22



                  substantially dependent on sales completed in the latter part
                  of that quarter, and revenue for any future quarter is not
                  predictable with any significant degree of accuracy.

                  STOCK MARKET AND STOCK PRICE 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, the
                  software industry or the securities markets in general. Such
                  factors include, but are not limited to, declines in trading
                  price that may be triggered by the Company's failure to meet
                  the expectations of securities analysts and investors. The
                  Company cannot provide assurance that in such circumstances
                  the trading price of the Company's common stock will recover
                  or that it will not experience a further decline. Moreover,
                  the trading price could be subject to additional fluctuations
                  in response to quarter-to-quarter variations in the Company's
                  operating results, material announcements made by the Company
                  or its competitors, conditions in the software industry
                  generally or other events and factors, many of which are
                  beyond the Company's control.

                  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 quickly to industry changes, 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

                                                                              23



                  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 and warranty costs, any of which could have
                  a materially adverse effect on the Company's business,
                  financial condition and results of operations.

                  DEPENDENCE ON DISTRIBUTORS: The Company continues to
                  distribute most of its products through its global network of
                  30 independent, regional ASDs. The ASDs sell ANSYS and
                  DesignSpace products to new and existing customers, expand
                  installations within their existing customer base, offer
                  consulting services and provide the first line of 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, 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 rather than the Company's 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, CAE and computer-aided manufacturing
                  ("CAM") markets are intensely competitive. In the traditional
                  CAE market, the Company's primary competitors include
                  MSC.Software Corporation and Hibbitt, Karlsson and Sorenson,
                  Inc. 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,
                  Electronic Data Systems Corporation and Dassault Systemes
                  provide varying levels of design analysis, 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 markets. 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

                                                                              24



                  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 its key technical and
                  other management employees. Although the Company has an
                  employment agreement with one executive, the loss of this
                  employee, 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
                  portion of the Company's business comes from outside the
                  United States of America. 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 certain international regions
                  have continued to experience 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 condition or results of
                  operations.

                     In November 2000, the United States enacted the FSC Repeal
                  and Extraterritorial Income Exclusion Act (the "Act") in
                  response to a challenge from the World Trade Organization
                  ("WTO") that the existing tax benefits provided by foreign
                  sales corporations were prohibited tax subsidies. The Act
                  generally repeals the foreign sales corporation and implements
                  an extraterritorial income ("ETI") tax benefit. Recently, the
                  European Union stated that it did not believe the ETI
                  provisions bring U.S. tax law into WTO-compliance and asked
                  the WTO to rule on the matter. On January 14, 2002, the WTO
                  ruled in favor of the European Union's charge. As a result,
                  there may be further related changes to U.S. export tax law in
                  connection with this ruling. Any such prospective changes
                  regarding tax benefits associated with the Company's export
                  sales may

                                                                              25



                  adversely impact the Company's effective tax rate and decrease
                  its net income in future periods.

                  DEPENDENCE ON PROPRIETARY TECHNOLOGY: The Company's success is
                  highly dependent upon its proprietary technology. Although the
                  Company was awarded a patent by the U.S. Patent and Trademark
                  Office for its web-based reporting technology, the Company
                  generally 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: The Company has
                  historically maintained stable recurring revenue from the sale
                  of monthly lease licenses and noncancellable annual leases for
                  its software products. More recently, the Company has
                  experienced an increase in customer preference for perpetual
                  licenses that involve payment of a single up-front fee and
                  that are more typical in the computer software industry. While
                  revenue generated from monthly lease licenses and
                  noncancellable annual leases currently represents a portion of
                  the Company's software license revenue, to the extent that
                  perpetual license revenue continues to represent a significant
                  percentage of total software license revenue, the Company's
                  revenue in any period will increasingly depend on sales
                  completed during that period.

                  RISKS ASSOCIATED WITH ACQUISITIONS: The Company has
                  consummated and may continue to consummate certain strategic
                  acquisitions in order to provide increased capabilities to its
                  existing products, enter new product and service markets or
                  enhance its distribution channels. The ability of the Company
                  to integrate the acquired businesses, including delivering
                  sales and support, ensuring continued customer commitment,
                  obtaining further commitments and challenges associated with
                  expanding sales in particular markets and retaining key
                  personnel, will impact the success of these acquisitions. If
                  the Company is unable to properly and timely integrate the
                  acquired businesses, there could be a materially

                                                                              26



                  adverse effect on the Company's business, financial condition
                  and results of operations.

                  GENERAL CONTINGENCIES: The Company is subject to various
                  investigations, claims and legal proceedings from time to time
                  that arise in the ordinary course of its business activities.
                  Each of these matters is subject to various uncertainties, and
                  it is possible that some of these matters may be resolved
                  unfavorably to the Company.

                                                                              27
