"instruction": "Work with OpenFOAM from the command line, then copy `/home/user/Desktop/cavity_base/` to `/home/user/Desktop/cavity_graph/` and solve a fixed two-dimensional lid-driven cavity. Source the installed OpenFOAM environment before running OpenFOAM commands. For this task, 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\nUse a `1 x 1 x 0.01 m` domain with exactly `(64 64 1)` uniform cells, empty front/back faces, no-slip stationary left/right/bottom walls, top-lid velocity `(1 0 0)` m/s, kinematic viscosity `0.01 m^2/s` (`Re=100`), and zero initial velocity. Run laminar `icoFoam` with `deltaT=0.005 s` through `t=30 s`, retain ASCII iteration-30 `U` and `p`, and save successful `blockMesh`, `checkMesh`, and solver outputs as `log.blockMesh`, `log.checkMesh`, and `log.icoFoam`; a failed mesh check is not acceptable. Create `system/sampleDict` using `cellPoint` interpolation and raw output. Sample `U` at exactly 99 uniformly spaced points per line: the vertical line starts at `(0.5,0.01,0.005)` and ends at `(0.5,0.99,0.005)`, while the horizontal line starts at `(0.01,0.5,0.005)` and ends at `(0.99,0.5,0.005)`; both therefore use coordinates 0.01 through 0.99 in increments of 0.01 and include coordinate 0.5. Run the sampling operation and save its output as `log.sample`. Create `/home/user/Desktop/postprocess.py` that parses the raw samples, writes `/home/user/Desktop/vertical_centerline.csv` with columns `y_m,ux_mps,uy_mps`, writes `/home/user/Desktop/horizontal_centerline.csv` with columns `x_m,ux_mps,uy_mps`, defines `ux_center` as vertical-profile `Ux` at `y=0.5`, defines `uy_center` as horizontal-profile `Uy` at `x=0.5`, and writes `/home/user/Desktop/summary.txt` as one CSV line `ux_center, uy_center`. Do not hard-code results and do not use GUI tools.",
