  "instruction": "Begin with a template where a beam and a solid are disconnected: `/home/user/Desktop/mpc_base.inp`. Run `ccx --version` or invoke the installed `ccx` binary from a terminal. For the steps below, 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. Modify and generate `/home/user/Desktop/mpc.inp`: Please save the final input file as /home/user/Desktop/mpc.inp. - Connect node 101 (beam end) to solid right-face nodes (`2,3,6,7`) - Or manually define equivalent displacement relations - Apply `FY=-100 N` at node 102 2. Submit the job and write a post-processing script to parse `mpc.dat`: - Extract node-102 `UY` - Extract node-101 `UY` - Extract average `UY` on solid right-face nodes (`2,3,6,7`) - Write to `/home/user/Desktop/summary.txt` in this format: `tip_u2,node101_u2,solid_face_avg_u2` 4. Do not use the CGX GUI.",
