Monthly summary for 2025-09 (uwsbel/chrono-wisc). Key feature delivered: FSI Demos Initialization Refactor using ChFsiProblem; centralized initialization/configuration and removal of direct ChFsiFluidSystemSPH::ReadParametersFromFile. Commit 688c20d2b4d423da9d500a8774187944f4006326.

August 2025: Focused on improving Chrono YAML modeling, documentation, and build reliability for uwsbel/chrono-wisc. Delivered a comprehensive Chrono YAML Schema and Documentation Improvements, strengthening collision/visualization geometry definitions, anchors for shapes/materials, support for external body loads, standardized property tables, and clarified orientation data. Also resolved a critical build issue by fixing missing header includes in the FSI WaveTank demo when CHRONO_PARDISO_MKL is not defined. These changes reduce modeling errors, improve usability, and ensure robust cross-configuration builds across environments.

June 2025 monthly summary for uwsbel/chrono-wisc: Implemented YAML-driven Multi-Body System (MBS) configuration to enable rapid, reproducible demos involving motors (stators, rotors, guides, sliders, obstacles) with actuation functions. Added and wired YAML definitions (motors.yaml, basic_mbs_motor.yaml) including time step, end time, integrator, and solver. Updated visualization by setting camera orientation to Z-up to align with the coordinate system and improve debugging visibility. This work reduces setup time for new scenarios, improves reproducibility, and enhances stakeholder visibility into the simulation pipeline.

May 2025 — uwsbel/chrono-wisc: Delivered a critical bug fix and observability enhancement in the SPH simulation pipeline. The symplectic integrator position update bug fix ensures updated positions correctly incorporate the 'w' component, preserving data integrity in the SPH module. PrintParams enhancement now displays the integration scheme (Explicit Euler, Runge-Kutta 2, Symplectic Euler, Implicit SPH), improving debuggability and parameter visibility. These changes improve numerical accuracy, reproducibility, and maintainability, delivering business value through more reliable simulations and easier configuration inspection.

February 2025 (uwsbel/chrono-wisc) focused on strengthening documentation, introducing a diffusion-based SPH shifting method, and conducting targeted experiments to understand shifting dynamics. Key deliverables include updated Chrono::GPU documentation, a diffusion-based shifting workflow with a refactored Navier–Stokes kernel, and a zero-shifting experiment in Couette flow to assess dynamic impact. Stability improvements were achieved through tuning free-surface thresholds and the diffusive parameter A, yielding a more accurate WaveTank pressure profile. These efforts enhance onboarding, enable robust GPU demos, and provide a solid foundation for physics analyses and future optimizations.

January 2025: Bibliography curation for uwsbel/BibFiles focused on expanding literature coverage for variable-geometry components and energy storage modeling. Added Husain et al. (2023) to refsFSI.bib and Schirck et al. (2023) to refsDEM.bib, supported by descriptive commit messages for traceability. No major bugs fixed this period; maintenance-focused enhancements completed to improve validation readiness and future referencing.

Month: 2024-12 — In uwsbel/chrono-wisc, delivered two major features that enhance realism, data analytics, and configurability of FSI simulations, with clear traceability to commits. No discrete bug fixes were recorded this month; efforts focused on robustness and reproducibility. The work enables faster iteration for design decisions and improves energy-extraction modeling through explicit PTO and logging capabilities.
