Important Features:

1. Enhancement of RAVEN Parallels and “RAVEN Runs RAVEN”: Improved parallel execution capabilities within RAVEN, including the ability for one instance of RAVEN to execute another, enhancing modularity and flexibility.
2. Leveraging PyDMD for Dynamic Mode Decomposition (DMD) Reduced Order Models (ROMs): Integration of the PyDMD library to create efficient and accurate reduced-order models using dynamic mode decomposition techniques.
3. Introduction of New Plugins: POEM and DOVE:

• POEM: A plugin designed for optimum experiment design (https://idaholab.github.io/POEM/)
• DOVE: (https://github.com/idaholab/DOVE)

4. Significant Batching Improvements for Hybrid and Ensemble Models: Enhanced batching processes to support complex hybrid models within ensemble models.
5. Addition of Multi-Resolution Time Series Analysis: Enhanced capabilities for analyzing time series data at multiple resolutions, improving the accuracy and depth of temporal data analysis.
6. Added SLURM Support for High-Performance Computing (HPC): Integration with SLURM workload manager to optimize resource allocation and job scheduling on HPC systems.
7. Implementation of Stopping Criteria in Code Interface: New feature allowing simulations to be prematurely stopped based on predefined criteria, improving efficiency and resource utilization.
8. Incorporation of Multi-Objective Optimization Algorithm (NSGA-II): Added support for the Non-dominated Sorting Genetic Algorithm II (NSGA-II) for solving multi-objective optimization problems.
9. Development of New MELCOR RAVEN Interface: New interface to seamlessly integrate RAVEN with MELCOR, a severe accident analysis code.
10. Introduction of New HTPIPE RAVEN Interface: Integration with HTPIPE, enhancing the simulation capabilities for heat transfer and fluid flow analysis.
11. Creation of New OpenFOAM RAVEN Interface: New interface facilitating the use of RAVEN with OpenFOAM, an open-source computational fluid dynamics (CFD) toolbox.
