Embedding reliable numerical analysis capabilities into an enterprise-wideinformation system

A simulation environment to support engineering design embedded in an enter prise-wide information system is presented. The environment consists of a s et of structures and managers housing the problem definition, tools for con trolling the simulation model construction and execution, and the interacti on of simulation processes with the product data management system. The iss ues associated with the introduction of automated and adaptive geometry-bas ed simulation processes into the engineering design process are emphasised.
