PROFILE
Ben Spencer
Worked on the idaholab/moose repository, delivering features and fixes that advanced solid mechanics, material modeling, and simulation reliability. Developed enhancements for Dynamic Solid Mechanics, including plane strain/stress support and robust input validation, and implemented the ElementExtremeMaterialPropertyReporter to compute and report extreme material property values. Improved XFEM robustness and test stability, addressed cross-platform discrepancies, and expanded regression testing for viscoelastic models. Contributed to documentation pipelines and parameter validation, ensuring clear user guidance. Leveraged C++, Python, and numerical methods to refactor code, optimize performance, and maintain test reliability, demonstrating depth in finite element analysis, software engineering, and technical writing.

Apr 1, 2026April 2026 monthly summary for idaholab/moose focusing on robustness, test stability, and expanded material modeling capabilities. Delivered a stability fix for long-term elasticity tensor that prevented downstream test failures, implemented as a temporary workaround to maintain test pass rates while root causes are addressed. Expanded the viscoelastic material model with a Poisson's ratio regression test to improve robustness and flexibility for long-term element specifications. Completed cleanup of the workaround once upstream fixes landed, consolidating code health and reducing future maintenance risk.

Jul 1, 2025July 2025 monthly summary for idaholab/moose: Delivered robust enhancements to Dynamic Solid Mechanics and input validation. Implemented weak plane strain and plane strain/stress support, corrected use_displaced_mesh handling, removed deprecated time integration parameters, and introduced isParamDefined with accompanying tests. Expanded 2D planar scenario testing and updated documentation with a related paper reference. Fixed multiple issues in DynamicSolidMechanicsPhysics (ref #31007), improving stability and reliability of simulations. Result: higher model fidelity, fewer configuration errors, and clearer user guidance for plane stress/strain workflows.

Jul 1, 2019July 2019: XFEM robustness enhancements and test stabilization in idaholab/moose. Implemented a new min_weight_multiplier parameter to XFEM to improve handling of quadrature weights and mitigate ill-conditioning in 3D problems with small material slivers. Updated test configurations to set min_weight_multiplier to 0.0 in targeted tests to reduce discrepancies and stabilize results. These changes improve numerical stability and reliability, and reduce flaky tests in regression suites. Commit references included for traceability and review: c36ff9cc5bb07b06d05f15f88f09cd6ae953f1c4 (Add min_weight_multiplier parameter for XFEM) and 6e87c3ecc0c1e63cbc9a25facd3eabf3c6347a58 (Decrease min_weight_multiplier for a few tests).
