brittle-numerics-root-cause
brittle-numerics-root-cause is a Physics, mathematics & simulation skill for AI agents, published by idaholab in the moose repository on GitHub. Skillspace rates brittle-numerics-root-cause D (59/100) and it passed the safety scan; the rating is based on static analysis only.
Use when a numerical calculation or test gives different results under compiler flags, optimization level, hardware, thread count, or execution order. Treat this as a symptom that some part of the algorithm is ill-conditioned (near-singular solve, an algebraically-truncated slowly-converging series, large cancelling terms) — not as flaky-test noise to suppress by pinning flags, loosening tolerances, or blindly regolding. Walks through instrumenting for real per-iteration data, finding the actual non-robust mechanism, validating a targeted fix against that data, and anticipating the blast radius on other tests before regolding.
