"instruction": "Using OpenFOAM from the command line, copy `/home/user/Desktop/shockTube_base/` to `/home/user/Desktop/shock_tube/` and solve the fixed Sod shock-tube problem. Source the installed OpenFOAM environment before running OpenFOAM commands. At the start of the 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 0.01 x 0.01 m` tube with exactly `(1000 1 1)` cells, zero-gradient end faces, empty transverse faces, and a diaphragm at `x=0.5 m`. The gas is calorically perfect with molecular weight 28.96 kg/kmol, `Cp=1004.5 J/(kg K)`, zero viscosity, and `gamma` approximately 1.4002. Set zero velocity everywhere. The left initial state is `p=100000 Pa`, `T=348.308740203735 K` (`rho=1 kg/m^3`); the right state is `p=10000 Pa`, `T=278.646992162988 K` (`rho=0.125 kg/m^3`). Run `blockMesh`, require a successful `checkMesh`, run `setFields`, and solve with `rhoCentralFoam` using `maxCo=0.2` through the exact sample time `t=0.0005 s`, retaining ASCII final `p`, `T`, and `U`. Save the outputs as `/home/user/Desktop/shock_tube/log.blockMesh`, `log.checkMesh`, `log.setFields`, and `log.rhoCentralFoam`; a failed mesh check is not acceptable. Write the final cell-centre field `C`. Define `shock_pressure` as the arithmetic mean of every final cell pressure whose centre satisfies `0.64 <= x <= 0.72 m`; this fixed interval must contain exactly 80 cells and have population standard deviation divided by its mean below 0.05. Create `/home/user/Desktop/postprocess.py` that reads the final `C` and `p`, writes all 1,000 cells to `/home/user/Desktop/pressure_profile.csv` with columns `x_m,p_pa`, and writes `/home/user/Desktop/summary.txt` as one line containing `shock_pressure` in Pa. Do not hard-code the result and do not use GUI tools.",
