| "instruction": "Create and solve `/home/user/Desktop/cylinder_fo/` for two-dimensional laminar crossflow over a circular cylinder with OpenFOAM from the command line. Source the installed OpenFOAM environment before running OpenFOAM commands. For the steps below, 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 cylinder diameter of 0.1 m centered at the origin, an empty span of 0.01 m, and an O-grid whose outer circular boundary has radius 1.0 m. Divide the outer boundary into an upstream inlet half and a downstream outlet half. Use a uniform inlet velocity `(1 0 0)` m/s, zero-gauge-pressure outlet, no-slip cylinder, density 1 kg/m^3, and kinematic viscosity 1e-3 m^2/s, so Re_D = 100. Build exactly 8 hexahedral sectors with `(40 12 1)` cells per sector, run laminar `pimpleFoam` with `deltaT = 0.0025 s` through `t = 20 s`, and retain the final `U` and `p` fields. Add an online `forceCoeffs` function object for the cylinder with `liftDir (0 1 0)`, `dragDir (1 0 0)`, `magUInf 1`, `lRef 0.1`, and `Aref 0.001`. Save successful `blockMesh`, `checkMesh`, and solver logs as `log.blockMesh`, `log.checkMesh`, and `log.pimpleFoam` in the case; a failed `checkMesh` is not acceptable. Create `/home/user/Desktop/postprocess.py` that reads the final `forceCoeffs.dat`, uses every sample in the fixed averaging window `10 <= t <= 20 s`, writes the complete coefficient history to `/home/user/Desktop/force_history.csv` with columns `time_s,cd,cl`, and writes `/home/user/Desktop/summary.txt` as one CSV line `avg_cl, avg_cd`. Do not hard-code result values and do not use GUI tools.", |
