  "instruction": "Complete a linear eigenvalue buckling analysis using ANSYS Workbench via the Command Line Interface (CLI). To start ANSYS Workbench, run `C:\\Program Files\\ANSYS Inc\\v261\\ansys\\bin\\winx64\\ANSYS261.exe -g` (version/path may differ on your machine). On this machine, launch ANSYS Workbench with `C:\\Program Files\\ANSYS Inc\\v261\\Framework\\bin\\Win64\\RunWB2.exe`.\n\nPhysical problem: A pin-ended straight column is subjected to axial compression. Coordinate system and geometry: - Use the global Cartesian coordinate system. - Model the column as a line body with a beam cross-section. - The column axis is along the global Y direction. - The bottom end is located at Y = 0 mm. - The top end is located at Y = 1000 mm. - The rectangular beam section is: - Width = 10 mm - Height = 10 mm Model parameters: - Line body length: 1000 mm - Section type: rectangular beam section - Section size: 10 mm × 10 mm - Material: Structural Steel with the following linear elastic properties: - Young's modulus E = 210000 MPa - Poisson's ratio ν = 0.3 - Use a consistent N-mm unit system. Boundary conditions: - Bottom end at Y = 0 mm: - Constrain UX = 0, UY = 0, and UZ = 0. - Leave all rotations free. - Top end at Y = 1000 mm: - Constrain UX = 0 and UZ = 0. - Leave UY free. - Leave all rotations free. - Apply an axial compressive reference load of 1 N at the top end in the negative global Y direction. Analysis type: - Linear eigenvalue buckling analysis. - Extract the first buckling mode. Save requirements: - Use C:\\Users\\user\\Desktop as the working location. - Save the Workbench project file as: C:\\Users\\user\\Desktop\\wb_buckling.wbpj - Save the MAPDL-equivalent database file as: C:\\Users\\user\\Desktop\\wb_buckling.db - Save the MAPDL-equivalent structural result file as: C:\\Users\\user\\Desktop\\wb_buckling.rst",
