| description | Custom OpenFOAM model implementation entry — alias for cfd-skills/cfd-code-modify. Use when the user wants to implement, modify, or add a custom viscosity / turbulence / source term / fvOption inside a case-local customModels directory. The full self-contained recipe (with the OPENFOAM 10 LITERATURE CHANGE AGENT v2 protocol embedded verbatim) lives in cfd-skills/cfd-code-modify/SKILL.md. |

cfd-code-mod (alias)
This skill is a thin alias for cfd-skills/cfd-code-modify/SKILL.md. The full ARIS/DS-style self-contained recipe — including the OPENFOAM 10 LITERATURE CHANGE AGENT v2 protocol embedded verbatim, the wmake compile-fix loop, and the smoke-test recipe — lives there.
Why an alias?
After the Nov 2026 ARIS/DS-style refactor, all recipe content moved to cfd-skills/. CLAUDE.md routing for "implement / modify / viscosity model / Bingham / power-law / Carreau / source term / fvOption" historically pointed here, so this file remains for backward compatibility.
Do this
- Open
cfd-skills/cfd-code-modify/SKILL.md.
- Follow Steps 1–7 there: build payload → resolve OpenFOAM API grounding → run the LITERATURE CHANGE AGENT (LLM call with the full v2 protocol embedded) → compile → compile-fix loop → smoke-test → write
build_result.json.
Hard rules (preserved from the original skills/cfd-code-mod)
- Never edit
$WM_PROJECT_DIR, $FOAM_SRC, or any OpenFOAM installation/source directory.
- All custom code lives in
<case_path>/customModels/<ClassName>/.
- Compile case-locally with
wmake libso. Link via controlDict.libs and one activation dictionary (constant/momentumTransport, constant/fvModels, or fallback constant/turbulenceProperties).
- One coherent in-family modification per invocation. Out-of-scope requests (new transported variables, solver edits, BC framework changes, multi-region, multi-physics outside kinematic viscosity) → return
UNSUPPORTED.
Cross-link
- Standard CFD research after a code mod → continue from Stage 2 of
cfd-skills/cfd-pipeline/SKILL.md (general path), with the mesh gate then running against the modified physics group.
- For OED of custom turbulence models, the code-mod is invoked inside
cfd-skills/cfd-open-discovery/SKILL.md's discovery loop, once per candidate.
