| "instruction": "With OpenFOAM from the command line, copy the supplied template `/home/user/Desktop/snappy_base/` to `/home/user/Desktop/cylinder_snappy/` and mesh the supplied `/home/user/Desktop/snappy_base/constant/triSurface/cylinder.stl` without geometric transformation (scale 1). Source the installed OpenFOAM environment before running OpenFOAM commands. On this machine, before running the case, load OpenFOAM with `source /opt/openfoam11/etc/bashrc`; the solver binaries are under `/opt/openfoam11/bin` and its platform bin directory.\n\nThe STL is a closed cylinder of diameter 0.1 m, length 0.01 m, and center `(0.5, 0.5, 0)` inside a fixed `2 x 1 x 0.01 m` domain. Generate a `(160 80 1)` background mesh, keep the fluid using `locationInMesh (0.1 0.5 0)`, use cylinder surface refinement levels `(2 3)`, enable snapping, and add exactly 3 cylinder layers with expansion ratio 1.2 and relative final-layer thickness 0.4. Run `surfaceFeatures`, `blockMesh`, `snappyHexMesh -overwrite`, and `checkMesh`; preserve their successful logs as `log.surfaceFeatures`, `log.blockMesh`, `log.snappyHexMesh`, and `log.checkMesh`, and do not accept a failed mesh check. Solve the incompressible steady external flow for exactly 500 SIMPLE iterations with `simpleFoam`, retaining the iteration-500 fields. Use inlet velocity `(3 0 0)` m/s, zero-gauge-pressure outlet, symmetry on the transverse domain boundaries, no-slip on the cylinder, density 1 kg/m^3, kinematic viscosity 1e-6 m^2/s (`Re_D = 300000`), and the realizable k-epsilon RANS model with inlet `k = 0.03375 m^2/s^2` and `epsilon = 0.1458 m^2/s^3`. Compute the final wall `yPlus` field; the target arithmetic mean of all cylinder boundary-face values is the wall-function interval `20 < avg_yplus < 80`. Create `/home/user/Desktop/postprocess.py` that reads the final `yPlus` field, writes every cylinder face value to `/home/user/Desktop/yplus_surface.csv` with columns `face_index,yplus`, and writes `/home/user/Desktop/summary.txt` as one line containing `avg_yplus`. Do not hard-code result values and do not use GUI tools.", |
