  "instruction": "Build and solve a modal analysis model of a fixed-fixed beam using ANSYS Mechanical APDL. To start ANSYS Workbench, run `C:\\Program Files\\ANSYS Inc\\v261\\ansys\\bin\\winx64\\ANSYS261.exe -g` (version/path may differ on your machine). For the steps below, launch ANSYS Workbench with `C:\\Program Files\\ANSYS Inc\\v261\\Framework\\bin\\Win64\\RunWB2.exe`.\n\nPhysical problem: Modal analysis of a straight beam fixed at both ends. Coordinate system and geometry: - Use the global Cartesian coordinate system. - The beam length is along the X direction. - The beam starts at X = 0 mm and ends at X = 500 mm. - The beam cross section is rectangular: - Width = 10 mm - Height = 10 mm Model parameters: - Element type: BEAM188 - Section type: rectangular beam section - Section size: 10 mm × 10 mm - Beam length: 500 mm - Mesh: 20 equal divisions along the beam length Material: - Use a consistent N-mm-s unit system. - Young's modulus: E = 210000 MPa, equivalent to 210000 N/mm² - Poisson's ratio: ν = 0.3 - Density: 7.85e-9 tonne/mm³, equivalent to 7850 kg/m³ Boundary conditions: - Fully constrain both beam ends: - At X = 0 mm: constrain UX, UY, UZ, ROTX, ROTY, and ROTZ. - At X = 500 mm: constrain UX, UY, UZ, ROTX, ROTY, and ROTZ. Analysis type: - Modal analysis - Extract the first 3 modes. Save requirements: - Use C:\\Users\\user\\Desktop as the ANSYS working directory. - Save the database file as: C:\\Users\\user\\Desktop\\apdl_fixed_beam_modal.db - Save the structural result file as: C:\\Users\\user\\Desktop\\apdl_fixed_beam_modal.rst",
