| "instruction": "The starting input is `/home/user/Desktop/aero_twrshadow_base.dat`, `/home/user/Desktop/tsr_scan.fst`, `/home/user/Desktop/elasto_tsr_base.dat`, and a complete NREL 5 MW dependency set. Additional initialization dependencies are pre-uploaded under `/home/user/Desktop` with relative structure preserved. Only initialization inputs are included; no answer/result artifacts are preloaded.\n\nCompare aerodynamic-power fluctuations with and without Powles tower shadow from the command line. The supplied NREL turbine is normally upwind, so use an explicit rigid downwind test geometry to make the tower wake intersect the rotor without a structural tower strike. 1. Write `/home/user/Desktop/build_case.py`. Create normalized `/home/user/Desktop/elasto_shadow.dat` with all blade, drivetrain, generator, yaw, and tower structural DOFs disabled, `RotSpeed=9 rpm`, and `OverHang=+20 m`. Generate `/home/user/Desktop/aero_notower.dat` with `TwrShadow=0` and `/home/user/Desktop/aero_tower.dat` with `TwrShadow=1`; request native `RtAeroPwr` from both. 2. Generate `/home/user/Desktop/case_notower.fst` and `/home/user/Desktop/case_tower.fst` with `TMax=30`, `DT_Out=0.1`, `OutFileFmt=1`, `CompServo=0`, the supplied steady 8 m/s inflow, and the matching AeroDyn file. Run both with `/home/user/miniconda3/bin/openfast`, retaining `/home/user/Desktop/case_notower.out`, `/home/user/Desktop/case_tower.out`, `/home/user/Desktop/case_notower.log`, and `/home/user/Desktop/case_tower.log`. 3. Write `/home/user/Desktop/postprocess.py`. For samples with `t >= 10 s`, convert `RtAeroPwr` from W to kW and calculate its population standard deviation for each case. Define `ratio_std = tower_std_kw/no_tower_std_kw`. At the fixed 1P frequency `9/60=0.15 Hz`, remove the mean and calculate single-sided sinusoidal amplitude `2*abs(sum((p-mean)*exp(-2*pi*i*f*t)))/N` for each case. 4. Save `/home/user/Desktop/summary.txt` as `no_tower_std_kw,tower_std_kw,ratio_std,no_tower_1p_amp_kw,tower_1p_amp_kw`. Do not use GUI tools.", |
