"instruction": "For this task, start with an OpenFAST linearization template. 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. Use the full OpenFAST executable path shown above.\n\nComplete a deterministic, tower-only structural linearization from the command line. 1. Copy `/home/user/Desktop/linear_base.fst` to `/home/user/Desktop/linear.fst`, then modify `linear.fst`: set `TMax=0.1`, `ModCoupling=1`, `CompElast=1`, `CompInflow=0`, `CompAero=0`, `CompServo=0`, `Gravity=0`, `Linearize=True`, `CalcSteady=False`, `NLinTimes=1`, `LinTimes=0.09`, `LinInputs=0`, `LinOutputs=0`, `LinOutJac=False`, and `LinOutMod=False`. 2. Modify `/home/user/Desktop/NRELOffshrBsline5MW_Linear_ElastoDyn.dat`: disable `FlapDOF1`, `FlapDOF2`, `EdgeDOF`, `DrTrDOF`, `GenDOF`, `YawDOF`, `TwFADOF2`, and `TwSSDOF2`; enable only `TwFADOF1` and `TwSSDOF1`; set `RotSpeed=0`. 3. Run `/home/user/miniconda3/bin/openfast linear.fst` from `/home/user/Desktop`. A successful run must generate the native files `/home/user/Desktop/linear.1.lin` and `/home/user/Desktop/linear.out`. 4. Write `/home/user/Desktop/postprocess.py` to parse the state matrix A from `linear.1.lin`, compute its eigenvalues, and distinguish the first tower fore-aft and side-to-side frequencies using the associated state/eigenvector participation. Run it to save `/home/user/Desktop/summary.txt` as exactly one line: `tower_fa_freq_hz,tower_ss_freq_hz`. Do not use GUI tools.",
