Heat Transfer Correlation Intelligence Engine. Deterministic, API-first correlation selection for single-phase convection — evaluates 13 correlations, ranks them with a reproducible scoring model, and reports confidence based on inter-method spread. Full traceability. Validated against Incropera 7th ed.
View docs →Python + Numba reimplementation of the General Ocean Turbulence Model (GOTM). Compiled single-column 1D ocean and lake physics — mean flow, turbulence closures (k-ε, k-ω, GLS, Mellor-Yamada), air-sea exchange, five ice thermodynamics models (including Winton three-layer sea ice and Holland-Jenkins ice-shelf basal melt), and FABM/pyfabm biogeochemistry coupling. Reads GOTM 6.x YAML configurations natively. Validates NetCDF output against Fortran GOTM 6.0.7 reference using a Fréchet-distance pipeline — all 22 official cases execute, default validation set (couette, channel, entrainment) passes. CLI, Python API, and warm JSON-RPC stdin/stdout daemon. No Fortran compiler required.
View docs →Local-first scientific workbench built around the pyGOTM kernel. Turns the simulation engine into a usable product: hash-pinned reproducibility manifests, a SQLite provenance DAG linking every artifact from raw data to published figure, a project bundle format (YAML + Parquet + NetCDF + Markdown) designed for Zenodo archival, and a NiceGUI browser UI with three vantage points (Operator / Modeler / Explorer). Includes a time-depth cinematic, scenario comparison, observation QC browser, YAML editor, report builder, and auto-collected citation graph. Runs entirely on-machine — no cloud account required. GPL/MIT process boundary: Studio calls the kernel via subprocess CLI and JSON-RPC, never as a linked import.
The honest story of pyGOTM — an open-source Python translation of GOTM that brings forty years of ocean turbulence physics into the language the next generation of scientists already uses. Ten weeks of failures, pivots, and one invented validation methodology.
A reflective look at what AI can and cannot replace in high-consequence engineering — and why the nuclear engineer doing safety analysis work is positioned for elevation, not obsolescence.
A first-person account of building htcie — a deterministic, audit-first correlation selection engine for single-phase convection heat transfer — and what I learned chasing correctness through primary sources.
