Feb 1, 2026February 2026 performance summary for loganoz/horses3d: Delivered substantive enhancements to the acoustic solver and reinforced parallel CFD reliability. Key features include a six-variable Qbase for the acoustic solver with the last variable representing squared speed of sound, plus startup precomputation to boost accuracy and startup performance; and parallel solver robustness improvements with enhanced debugging and more reliable base-solution handling. Major bug fixes address MPI communication robustness in the CAA Riemann solver and MPI_Face storage handling to prevent runtime errors across processes. Overall impact: higher solution accuracy, reduced cross-process failures, and improved maintainability due to clearer parameter naming. Technologies/skills demonstrated include MPI-based parallel solver design, precomputation strategies, debugging instrumentation, and maintainability improvements.

Dec 1, 2024December 2024 — Monthly performance summary for loganoz/horses3d: Implemented Immersed Boundary Method (IBM) source term integration for Incompressible Navier-Stokes (INCNS) and Multiphase solvers. The IBM source term is now computed and applied within the QDot arrays, with support for active IBM scenarios (non-moving boundaries). This port aligns with each solver’s conserved variables and does not yet include moving boundaries, wall models, or semi-implicit treatment. Commit 86c8176368990fa7fcb3f37e42f135a4df4468fb formalized the changes.
