What is RCE?

RCE is an Open Source distributed, workflow-driven integration environment. It is used by engineers and scientists to design and simulate complex systems (e.g., aircraft, ships, or satellites) by using and integrating their own design and simulation tools.
An overview about RCE and some of its application fields gives this survey article.
