| "instruction": "Begin with the incomplete OpenFOAM template `/home/user/Desktop/cavity_base/`. 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 two-dimensional laminar channel-flow case. 1. Write `/home/user/Desktop/build_case.py` and create `/home/user/Desktop/channel/`. Use a channel length of 1.0 m, height of 0.1 m, and one-cell span of 0.01 m with `frontAndBack` set to `empty`. Generate a uniform `100 x 80 x 1` block mesh. 2. Use kinematic viscosity `nu=1.0e-5 m^2/s`. Set the inlet mean speed to `0.1 m/s` and prescribe the fully developed plane-Poiseuille profile `Ux(y)=6*0.1*y*(0.1-y)/0.1^2` using 80 face-centered values. Use no-slip top and bottom walls, zero-gradient outlet velocity, zero-gradient inlet pressure, and outlet kinematic pressure `p=0`. This gives `Re_H=1000` and theoretical `u_max=0.15 m/s`. 3. Configure `icoFoam` with `deltaT=0.02 s`, `endTime=30 s`, ASCII output, and sufficiently tight linear-solver tolerances. Source `/opt/openfoam11/etc/bashrc`, run `blockMesh -case /home/user/Desktop/channel` and retain `/home/user/Desktop/channel/log.blockMesh`; then run `icoFoam -case /home/user/Desktop/channel` and retain `/home/user/Desktop/channel/log.icoFoam`. Both commands must complete successfully and the final time directory must be 30 s. 4. Create `/home/user/Desktop/channel/system/sampleDict` and sample `U` on 80 uniformly spaced points at `x=0.99 m`, `z=0.005 m`, from `y=0.000625 m` to `y=0.099375 m`. Write `/home/user/Desktop/postprocess.py`; it must run OpenFOAM `postProcess` for that sampling dictionary, retain `/home/user/Desktop/channel/log.sample`, and write `/home/user/Desktop/outlet_profile.csv` with `y_m,ux_cfd_mps,ux_theory_mps,abs_error_mps`. 5. Compute the sampled maximum axial velocity, the theoretical maximum `0.15 m/s`, and the maximum absolute profile error normalized by `0.15 m/s` as a percentage. Save `/home/user/Desktop/summary.txt` as `u_max_cfd_mps,u_max_theory_mps,max_profile_error_percent`; require the full-profile error to be at most 2%. Do not use ParaView or other GUI tools.", |
