                                                                    Exhibit 99.1

                      ANSYS Completes Acquisition of Fluent

     SOUTHPOINTE, Pa., May 1 /PRNewswire-FirstCall/ -- ANSYS, Inc. (Nasdaq:
ANSS), a global innovator of simulation software and technologies designed to
optimize product development processes, and Fluent Inc., a global provider of
computer-aided engineering (CAE) simulation software, today announced that ANSYS
has completed its acquisition of Fluent in a series of mergers for approximately
6,000,000 shares of ANSYS common stock and approximately $299 million in net
cash.

     ANSYS expects the acquisition to be immediately accretive to earnings,
excluding acquisition-related costs, amortization of intangibles, the impact of
deferred revenue purchase accounting treatment and expensing of stock options.
The company used a combination of existing cash and proceeds from approximately
$200 million of committed bank financing to fund the transaction.

     Fluent Inc. is a global supplier of CAE simulation software technologies
and services. Fluent products utilize computational fluid dynamics (CFD)
principles and techniques to enable engineers and designers to simulate fluid
flow, heat and mass transfer, and related phenomena involving turbulent,
reacting, and multiphase flow. The company's products are used by blue chip
companies, small and medium size enterprises, and academic institutions and
institutes around the world. Today, CFD simulation technology is used in almost
every industry sector and manufactured product.

     "With the acquisition of Fluent, ANSYS has significantly broadened its
offerings in the simulation market. I expect ANSYS to be an important partner to
design engineers in industries, from discrete manufacturing, oil and gas,
chemicals, food processing, as well as to environmental scientists studying how
pollution propagates and oceanographers trying to predict the effects of global
warming. Ships, airplanes, cars, your PC, home, office building and the
environment -- all will work better, be more efficient, pollute less or be
better managed as a result of a better understanding of the dynamics of the
gases and liquids in which, and with which, they operate," commented Daratech
CEO Charles M. Foundyller.

     Jim Cashman, ANSYS President and CEO added, "Finalizing the acquisition of
Fluent is great news for us, our customers and partners. We are very excited to
be able to move forward today as a unified company and begin executing our
strategy for the future."

     "With the operations and technology synergies that Fluent and ANSYS share,
we are confident that we can meet the needs of the CAE community for simulation
software and services in a highly effective manner," said Dr. Ferit Boysan, Vice
President and General Manager, Fluids Business Unit.

     The combination of ANSYS' and Fluent's software products and services is
expected to give ANSYS one of the most comprehensive, independent engineering
simulation software offerings in the industry, reaffirming and strengthening
ANSYS' commitment to open interface and flexible simulation solutions that are
primarily driven by customer demand and choice. With over 40 direct sales
offices and 17 development centers, on three continents, the combined company
will employ approximately 1,350 people.

The company expects to provide updated financial guidance with respect to Fluent and the financial outlook of the combined company in the next couple of weeks. About ANSYS, Inc.
