  "instruction": "With OpenFOAM from the command line, copy `/home/user/Desktop/dynamic_base/` to `/home/user/Desktop/dynamic/` and solve the fixed moving-cylinder case. Source the installed OpenFOAM environment before running OpenFOAM commands. Before starting the work, 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\nKeep the template's body-fitted 20-block, 1,800-cell mesh around the circular cylinder of radius 1 m and span 2 m, with nominal outer limits `x=-5..5 m` and `y=-1.5..2.5 m`. Use inlet velocity `(0.5 0 0)` m/s, zero-gauge-pressure outlet, slip upper/lower boundaries, density `1 kg/m^3`, kinematic viscosity `0.01 m^2/s` (`Re_D=100`), and laminar flow. Use `topoSet` with a cylinder of radius 1.41 m about the z axis to create the near-body cell zone `movingZone`. Configure the OpenFOAM 11 `motionSolver` mesh mover with the `solidBody` solver on that zone. The cylinder and near-body mesh oscillate rotationally about `(0 0 0)` with amplitude `(0 0 5)` degrees and angular frequency `2*pi rad/s` (1 Hz). Run `blockMesh`, require successful initial `checkMesh`, run `topoSet`, then run `pimpleFoam` with `deltaT=0.001 s` through the exact final time `t=2 s`, writing fields every 0.25 s. Require a successful final `checkMesh -latestTime`. Save logs as `/home/user/Desktop/dynamic/log.blockMesh`, `log.checkMesh`, `log.topoSet`, `log.pimpleFoam`, and `log.checkMeshFinal`; failed mesh checks are not acceptable. Add an online `forces` function object on `cylinder` with `rhoInf=1` and `CofR=(0 0 0)`. This case has no porosity model, so OpenFOAM 11 writes pressure and viscous force vectors only. Define `final_fx` as the sum of the pressure and viscous x-force components in the last `forces.dat` row at exactly `t=2 s`. Create `/home/user/Desktop/postprocess.py` that writes the complete force history to `/home/user/Desktop/force_history.csv` with columns `time_s,pressure_fx_n,viscous_fx_n,total_fx_n` and writes `/home/user/Desktop/summary.txt` as one line containing `final_fx`. Do not hard-code results and do not use GUI tools.",
