| "instruction": "Work from a frequency-analysis cantilever deck `/home/user/Desktop/modal_dynamic_base.inp`. Run `ccx --version` or invoke the installed `ccx` binary from a terminal. At the start of the task, use `/usr/bin/ccx` for the CalculiX solve and `/usr/bin/cgx` when CGX processing is needed.\n\nComplete the following from the command line: 1. Copy/extend it as `/home/user/Desktop/modal_dyn.inp`, keeping the existing `*Frequency, Storage=YES` step as the first step so the modal data and the following modal-dynamic step belong to the same `modal_dyn` job. 2. Add a second step using `*Modal Dynamic` with initial increment `0.001 s` and total time `0.1 s`. Apply a total `FY=-100 N` to the four nodes in the `Tip` node set (`-25 N` per node), keep the `Fixed` set constrained, and request `U` using both `*Node Print, Nset=Tip, Frequency=1` and `*Node File, Nset=Tip`. 3. Run `ccx modal_dyn`; the successful job must create `modal_dyn.dat`, `modal_dyn.frd`, and `modal_dyn.eig`. 4. Write `/home/user/Desktop/postprocess.py` to parse every printed Tip displacement block in `modal_dyn.dat`, average `UY` over the four Tip nodes at each time, and write `/home/user/Desktop/summary.txt` as `peak_abs_mean_tip_uy_mm, final_mean_tip_uy_mm`, where the first value is the maximum absolute mean Tip `UY` and the second is the mean Tip `UY` at `t=0.1 s`.", |
