| "instruction": "The incomplete OpenFOAM template `/home/user/Desktop/pipe_base/` is provided. The uploaded template is an editable input only; no result or answer artifacts are preloaded. Source `/opt/openfoam11/etc/bashrc` before running OpenFOAM commands.\n\nFrom the command line, build and solve a deterministic turbulent pipe case. 1. Write `/home/user/Desktop/build_case.py` and create `/home/user/Desktop/pipe_turb/`. Model a 5-degree axisymmetric wedge of a circular pipe aligned with x, with radius `R=0.05 m`, diameter `D=0.10 m`, and length `L=3.0 m` (30D). Use one conformal `300 x 20 x 1` block (6,000 cells), one cell through the wedge, an empty collapsed axis, two wedge patches, and a no-slip outer wall. The radial spacing is uniform; the acceptance target for the resulting whole-wall average is `20<=avg_yplus<=100`. 2. Set a uniform inlet `U=(15 0 0) m/s`, outlet kinematic pressure `p=0`, constant kinematic viscosity `nu=1.5e-5 m^2/s`, and reporting density `rho=1.225 kg/m^3`, so `Re_D=100000`. Use RAS `kOmegaSST`, inlet `k=0.84375 m^2/s^2`, inlet `omega=250 1/s`, and standard `kqRWallFunction`, `omegaWallFunction`, and `nutkWallFunction` wall conditions. 3. Configure `simpleFoam` for exactly 2000 SIMPLE iterations, ASCII output only at iteration 2000, bounded linear-upwind velocity convection, and upwind `k`/`omega`. Source `/opt/openfoam11/etc/bashrc`, run `blockMesh -case /home/user/Desktop/pipe_turb` and retain `pipe_turb/log.blockMesh`, then run `simpleFoam -case /home/user/Desktop/pipe_turb` and retain `pipe_turb/log.simpleFoam`; both must finish with `End`, and iteration 2000 must exist. Run `postProcess -case /home/user/Desktop/pipe_turb -latestTime -func writeCellCentres` and retain `pipe_turb/log.cellCentres`. Run `postProcess -case /home/user/Desktop/pipe_turb -solver incompressibleFluid -latestTime -func yPlus` and retain `pipe_turb/log.yPlus` and `pipe_turb/2000/yPlus`. 4. Write `/home/user/Desktop/postprocess.py`. Treat the 20 outlet-adjacent cell centers at `x>2.99 m` as annular samples sorted by radius. Integrate the full-circle outlet mass flow as `rho*sum(Ux_i*pi*(r_outer_i^2-r_inner_i^2))`, using the 20 uniform radial annuli, and save `/home/user/Desktop/outlet_profile.csv` with `radius_m,ux_mps,annulus_area_m2,mass_flow_kgps`. Read all 300 outer-wall values from the OpenFOAM-generated `2000/yPlus`, calculate their arithmetic mean, and save `/home/user/Desktop/wall_yplus.csv` with `wall_face_index,yplus`. 5. Save `/home/user/Desktop/summary.txt` as exactly `mass_flow, avg_yplus` in `kg/s` and dimensionless units. Do not use ParaView or other GUI tools.", |
