CAELESTIS Interoperable Simulation Ecosystem architecture and PRESS analysis

This deliverable reports the results of the first phase of WP2. It includes the definition of the architecture for the CAELESTIS Interoperable Simulation Ecosystem (ISE) which is the main outcome of Task 2.1, the mechanism for integrating several simulation software and managing the digital thread which is the main outcome of Task 2.2. As part of Task 2.3, we also provide the implementations details of the first prototypes for Hybrid Twin Platform and the HPC Simulation Service as the main components of the CAELESTIS ISE. Finally, we include cybersecurity analysis and recommendations for the CAELESTIS ecosystem as result of Task 2.5.
