Fluent Inc to Deliver Interoperability Solutions Built on PTC's Granite One

Agreement brings thermal modeling expertise to PTC customers and prospects.

Lebanon NH - October 29, 2002-Fluent Inc., a world leader in providing innovative engineering solutions using Computational Fluid Dynamics, announced today that it has signed an agreement with PTC (Nasdaq: PMTC), the Product Development CompanyÔ, to offer interoperability solutions built on PTC's Granite One.

Granite One is the interoperability platform based on the unmatched geometry, feature and data exchange capabilities at the core of Pro/ENGINEER, PTC's market leading mechanical computer-aided design software. One of the key advantages of solutions built on Granite is the ability to interoperate associatively, providing updates to downstream applications based on any changes in an original solid model.

Under the agreement, Fluent Inc will utilize Granite to provide interoperability between a range of MCAD solutions and its electronics cooling thermal management software, Icepakä. The integration of Granite One will enable Icepak users to share native Pro/ENGINEER part and assembly data. This data, or the data from any other Granite Application will drive associative update to Icecadä applications. Icepak will be further enhanced by leveraging Granite for neutral file exchange (e.g.,IGES, STEP) with other CAD solutions

"PTC's strength in electronics packaging dictates a need for a variety of thermal modeling applications, says Jim Heppelmann, PTC's chief technology officer and executive vice president, software products. "We know that our customers are excited about this new relationship as the Icepak application directly impacts their ability to innovate new products. Fluent Inc. is a wonderful addition to the Granite community, which is dedicated to making product development as easy and seamless as possible for our mutual customers." says Jim Heppelmann, PTC's chief technology officer and executive vice president, software products.

"By using Granite in our next generation CAD import module, we will enable our Icepak customers to read in CAD files from virtually anywhere and take advantage of the robust interoperability that we have provided on the Pro/ENGINEER platform for several years with our IcePro module," says Icepak Product Manager, Dr. Rajesh Nair.
