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.
Follow us on for latest news concerning releases, talks, related science etc. Check our YouTube channel for screen casts and other nice stuff concerning RCE.

Work with us

We are always open to working together with users to extend RCE and to apply it to new use cases. For this, we often participate in collaborative research projects. Please contact us at rce@dlr.de.


Release 6.1.0

Workflow Components

  • Added new component: Switch
    • Directs data on the base of a condition to one of two outputs
  • Added new component: Design of Experiments (DOE)
    • Supports sampling of a bounded solution space
  • Converger: Replaced "maximum iterations" by "maximum convergence checks"
  • Parametric Study: Added option "fit to bounds"
  • Optimizer
    • Added …

Release 6.0.2

  • Fixed tool integration wizard, which failed to integrate a tool under some certain circumstances
  • Converger and optimizer component sent value, whether the loop was converged/optimized on each iteration again (In 6.0.0 and 6.0.1, it was sent only once at the end as loop was converged …

Release 6.0.0

Workflow Editor

  • Components in a workflow can now be temporarily disabled: during workflow execution, these components and all their connections are treated as if they didn't exist
  • Added an option to show the number of connections represented by a line between two components
  • The connection editor dialog can now be …

Release 5.2.0


  • Improved clean up of RCE's temp directory


  • General performance improvement in workflow data browser
  • Fixed handling of scripts that were openend in an editor at the same time and that belong to different script components

Workflow components

  • Optimizer component
    • Improved behavior if optimizer fails or isn't available at …

Release 5.1.0


  • Added a view to execute RCE console commands
  • Added miscellaneous context menu entries for faster access to key features (such as integrating a new tool or creating the workflow examples project)
  • Fixed short cut for renaming workflow nodes (it is just F2 now)
  • Improved visibility of self-connections of components …
