  "instruction": "Work from a CalculiX beam-element template `/home/user/Desktop/beam_rect.inp`. Run `ccx --version` or invoke the installed `ccx` binary from a terminal. Use `/usr/bin/ccx` for the CalculiX solve and `/usr/bin/cgx` when CGX processing is needed.\n\nNote that in CalculiX, `B32` is a 3-node quadratic beam element, but the current model defines only 2 nodes. Complete the following from the command line: 1. Modify and generate `/home/user/Desktop/beam.inp`: Please save the final input file as /home/user/Desktop/beam.inp. - Insert middle node 3 between nodes 1 and 2 (coordinates `50,0,0`) - Change element 1 connectivity to `1,3,2` (`B32` requires 3 nodes) - Define a `10×10 mm` rectangular section - Fully constrain node 1 (`1,2,3,4,5,6`) - Apply `FY=-100 N` at node 2 2. Submit the job and write a post-processing script to parse `beam.dat`: - Extract node-2 `UY` (deflection) - Extract element-1 Mises stress (from `S11`, axial stress in beam) - Write to `/home/user/Desktop/summary.txt` in this format: `tip_uy, max_mises`",
