What does the Comet Workspace do?

Comet is a tool-neutral environment for performing integrated modeling and process automation for standard, well-defined and repeatable design simulation activities

* Capture/reuse engineering IP/best practices* Perform more robust mixed-fidelity trade studies* Collaborate across the project team* Reduce manual re-work and errors* Decisions based on consistent simulation results

- All disciplines work off the same (pedigreed) data* Audit trail of project models & results

STOP Project: Business Results & Conclusions

• Achieved greater level of understanding of how changes within one domain affect other domains – systems engineering approach is facilitated across silos

• Gained greater insight into how/why the sensor design worked– Project Dashboard enabled visualization and team review of

interdisciplinary design issues in one system-level view• Gained higher level of confidence in the accuracy of the sensor

analysis – eliminated hand-off errors between discipline silos• STOP analysis cycle time reduced by at least a factor of 2X –

each new analysis iteration increased the savings further• Conducted real-time design reviews with program management

and customers within the Comet Workspace without the need for separate PowerPoint snapshots of design status

– Full system reviews, comparing predictions to requirements– Interactive 3-D data available for the reviews

A New Core Capability was DemonstratedAbility to rapidly perform High Fidelity STOP Analysis

Customer gained system insights quickly, at a much lower relative cost.
