List the OpenFOAM solver templates this server can scaffold, with a one-line description of each and when to use it.

Estimate the wall-normal first-cell height needed to hit a target y+ on a turbulent boundary layer (flat-plate correlation). Use before meshing to set the near-wall cell size. Defaults are for air at sea level.

Predict the y+ that a given first-cell height will produce, and whether it lands in the viscous sublayer, buffer layer (avoid), or log-law region.

Reynolds number, laminar/transitional/turbulent classification, and a turbulence-model recommendation. geometry = 'internal' (pipe/duct) or 'external' (plate/bluff body/airfoil).

Compute inlet k, epsilon, omega and nut from turbulence intensity (fraction, e.g. 0.05) and turbulent length scale (m). Use to fill the 0/ directory inlet/internalField values for a RANS case.

Maximum/target transient time step from a target Courant number (dt = Co * dx / U).

Create a runnable OpenFOAM case skeleton at case_dir for the chosen solver (simpleFoam / pimpleFoam / icoFoam). Writes system/, constant/ and 0/ with a single-block box mesh (patches: inlet, outlet, walls, frontAndBack) and consistent turbulence fields.

openfoam_flavor selects the case style:

• 'classic' (default): application ; + transportProperties. Validated on ESI v1912; works on ESI v2006+ and Foundation v8-v10.

• 'foundation-v12': application foamRun; solver incompressibleFluid; + physicalProperties. Targets OpenFOAM Foundation v11/v12. Run blockMesh, then <solver> (classic) or foamRun (foundation-v12).

Read an OpenFOAM dictionary file. If entry is given (foamDictionary path syntax, e.g. 'endTime' or 'solvers/p/solver') and OpenFOAM is installed, return just that entry's value; otherwise return full contents.

Set a keyword in a dictionary file. Uses foamDictionary when available (supports nested entries like 'solvers/p/tolerance'); otherwise falls back to editing a top-level single-line entry as text.

Set (or insert) the boundaryField entry for a patch in a 0/ field file, e.g. field_file='0/U', patch='inlet', bc_type='fixedValue', value='(10 0 0)'.

Logically validate a case directory: required system files present, solver read, turbulence fields consistent with the model, and 0/ boundary patches matching the mesh. Returns errors, warnings and a pass flag. Does not require OpenFOAM to be installed.

Parse an OpenFOAM solver log file and report per-field residual drop, Courant number, bounded fields, and a convergence verdict (converged / diverging / NaN / still running).

Run a whitelisted OpenFOAM utility (blockMesh, checkMesh, foamDictionary, renumberMesh, decomposePar, foamListTimes, surfaceCheck, transformPoints) inside a case directory. Requires OpenFOAM installed and its environment sourced. Returns return code and the tail of stdout/stderr.

Turn a plain-language goal (e.g. 'flow through a pipe', 'drag on a car') into a complete setup plan: recommended solver, turbulence model, target y+, which blockMesh preset to auto-generate, the 0/ fields needed, per-patch boundary conditions, and a numbered step list. If velocity/length are missing it returns targeted questions to ask the user first. Start here.

List the auto-blockMesh geometry presets (channel, flatplate, step, box).

Auto-generate a valid, boundary-layer-graded blockMeshDict and write it to output_path (typically '/system/blockMeshDict'). Pick a preset (channel, flatplate, step, box). If first_cell_height > 0, wall-normal grading is computed automatically so the near-wall cell matches that height (feed it the value from the first_cell_height tool to hit a target y+). This removes the hardest, most error-prone part of setting up a case.

Analyze an STL surface (ASCII or binary): triangle count, bounding box, surface area, enclosed volume, and a watertight/closed-manifold check with the count of unpaired edges — plus a suggested background cell size and snappyHexMesh advice. No OpenFOAM needed. Use before snappyHexMesh.

Parse a checkMesh log file into a quality verdict: max/avg non-orthogonality, skewness, aspect ratio, pass/fail, and concrete fvSchemes/fvSolution advice (e.g. nNonOrthogonalCorrectors). Works from a saved log without OpenFOAM installed.

Darcy friction factor (Colebrook-White for turbulent, 64/Re laminar) and Darcy-Weisbach pressure drop / head loss for pipe flow. Defaults are for water; set roughness (m) for rough pipes. Handy sanity check against CFD.

Convective heat-transfer coefficient for internal flow (Dittus-Boelter Nu = 0.023 Re^0.8 Pr^n; laminar Nu = 3.66). Defaults are for water. Returns Nusselt number and h (W/m^2K).
