PROFILE
Eric Sandall
Ethan Sandall contributed to the solidsgroup/alamo repository by developing and refining computational fluid dynamics simulation workflows, focusing on channel and Couette flow scenarios. He enhanced simulation accuracy and stability through parameter tuning, adaptive mesh refinement, and improved boundary condition handling, leveraging C++ and Python for both code and input-driven changes. Ethan introduced regression testing infrastructure and automated test suites to validate numerical methods and entropy fixes, supporting reproducible and reliable results. His work included code documentation improvements and configuration management, enabling faster iteration and maintainability. The depth of his contributions advanced both simulation fidelity and the robustness of the codebase.

Mar 1, 2025March 2025 performance and delivery summary for solidsgroup/alamo. Delivered Roe entropy fix improvements with a refactor to an integer-based mechanism to support distinct implementations, and upgraded the regression test suite to validate multiple entropy-fix implementations. Also adjusted the FlowRiemannShockTube test input to ensure the entropy fix is exercised during regression testing, increasing test coverage and reliability.

Feb 1, 2025February 2025 monthly summary for solidsgroup/alamo focusing on numerical stability, regression testing, and test infrastructure improvements. Notable work includes a toggle for Roe entropy fix to enable safe experimentation, stabilization of Roe entropy corrections, and a broadened regression suite across major workflows. While the normal-into-wall case now works, FlowDrivenCavity remains a known failing scenario that has informed next steps. Regression tests were expanded and completed for several paths, and performance-oriented tests were added to improve validation speed and coverage. Overall, these changes reduce production risk, accelerate feedback, and enhance the reliability of flux calculations in production runs.
