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.
If you're interested in contributing to RCE please don't hesitate and contact us. The source code is distributed as a zip archive along with each release. We will provide general public access to our source code repository soon.
