There is a lot of detail involved in the design of gas- and chemical-delivery process modules in manufacturing, especially for the semiconductor industry. Celerity Inc. decided to ask for help from a software company primarily known for its simulation software. But MSC.Software, developer of MSC/NASTRAN, also provides services, and as part of that activity the company worked with Celerity to integrate Dassault Systemes' SmarTeam product-data management software. Celerity will use SmarTeam for accessing multiple CAD, BOM (bills of material), and document-handling systems. "PDM is an important part of any manufacturer's information technology infrastructure, especially as it relates to linking virtual product development data to BOM and other procurement data," says MSC Chairman Frank Perna.
