May 2025 - uwsbel/BibFiles: Focused bibliography update to support ongoing granular materials research. Added two BibTeX entries for recent papers: (1) granular shear flow lift/drag on intruders; (2) scientific machine learning for granular material simulations. Each entry includes arXiv ID, primary classification, and a URL. Changes were implemented with two small, review-friendly commits, preserving repository stability. This work strengthens literature coverage, enables faster citation, and supports reproducibility and collaboration across the team. No major bugs fixed this month in this repository. Overall, the update improves research documentation and accelerates knowledge sharing, aligning with business goals of traceable references and reporting readiness. Technologies used: BibTeX formatting, metadata management (arXiv IDs, classifications), version control, and literature curation.

Concise monthly summary for 2025-04 across two repositories, focusing on key business value and technical accomplishments. The main outcomes are a critical SPH demo bug fix that corrects periodic boundary handling along the Y-axis, and comprehensive bibliography maintenance with standardized BibTeX entries. These changes improve simulation fidelity, reproducibility, and citation consistency for research outputs.

March 2025 — uwsbel/chrono-wisc: Major SPH and domain-management overhauls delivering performance, stability, and domain-control improvements for robust FSI demos. Key outcomes include a memory-efficient extended active domain, a zombie-domain mechanism for deactivating out-of-bound particles, explicit non-periodic boundary handling with bounded neighbor searches, and refined domain extents for object-drop and BCE scenarios; plus SPH stability fixes and clearer FSI labeling. The work enabled faster runtimes, reduced cross-boundary checks, and more reliable simulations across boundary and FSI cases.
