| "instruction": "The starting input is 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 lid-driven cavity at Reynolds number 1000. 1. Write `/home/user/Desktop/build_case.py` and create `/home/user/Desktop/cavity/` as a 1.0 m by 1.0 m square with one 0.01 m spanwise cell and `frontAndBack` set to `empty`. Use a uniform `50 x 50 x 1` block mesh. 2. Set the top `movingWall` velocity to `(1 0 0) m/s`, all other walls to no-slip, and use kinematic viscosity `nu=1.0e-3 m^2/s`; therefore `Re=U*L/nu=1000`. Use zero normal pressure gradient on every wall and the usual pressure reference. 3. Configure `icoFoam` with first-order Euler time integration, central linear convection, `deltaT=0.005 s`, `endTime=30 s`, ASCII output, and write every 1000 time steps. Source `/opt/openfoam11/etc/bashrc`, run `blockMesh -case /home/user/Desktop/cavity`, retain `/home/user/Desktop/cavity/log.blockMesh`, then run `icoFoam -case /home/user/Desktop/cavity` and retain `/home/user/Desktop/cavity/log.icoFoam`; both commands must end successfully and the 30 s field must exist. Run `postProcess -case /home/user/Desktop/cavity -latestTime -func writeCellCentres` and retain `/home/user/Desktop/cavity/log.cellCentres`. 4. Write `/home/user/Desktop/postprocess.py`. From the final ASCII `C` and `U` fields, define the velocity at each requested coordinate as the component-wise average of the four nearest cell centers. Save `/home/user/Desktop/center_velocity.csv` with header `location,ux_mps,uy_mps,uz_mps` and rows for `center=(0.5,0.5,0.005)`, `left_mid=(0.25,0.5,0.005)`, and `right_mid=(0.75,0.5,0.005)`. The clockwise primary vortex must give center `Ux<0`, left-mid `Uy>0`, and right-mid `Uy<0`. 5. Save `/home/user/Desktop/summary.txt` as one finite scalar `center_ux_mps`; it must exactly report the center `Ux` derived above. Do not use ParaView or other GUI tools.", |
