PROFILE
Bhargav Sriram Siddani
Developed a robust multilevel ensemble simulation framework for the AMReX-FHD/FHDeX repository, focusing on enhanced particle handling and ensemble analysis. Leveraged C++ and Python to implement cross-level flux and particle data management, enabling accurate conservation analysis along the x-direction. Improved build and configuration workflows using Makefile scripting, reorganizing project structure to streamline ensemble deployment and reproducibility. Introduced max_level-based assertions and uniform initialization to stabilize core simulation routines, while adding flexible input options for particle-free and level-0 sample runs. These contributions improved the scalability, accuracy, and maintainability of ensemble simulations, supporting both production and research applications in high-performance scientific computing.

Oct 1, 20252025-10 monthly summary for AMReX-FHD/FHDeX: Delivered a robust multilevel ensemble simulation framework with enhanced particle handling and ensemble analysis, along with substantial build/config and initialization improvements. Key outcomes include cross-level flux/particle data handling with ensemble-mode particle initialization/management and ensemble data post-processing for conservation analysis along the x-direction. Reorganized project structure and build workflow to support ensembles, ensured correct source directories during builds, and expanded external potential handling and ensemble direction configurations. Core stability improvements include max_level-based assertions, uniform phi initialization, and new input variants (particle-free runs and a level-0 particle sample) to streamline testing and replication. These changes collectively improve accuracy, scalability, and maintainability for ensemble simulations in production and research use.
