| "instruction": "Build and solve a coupled thermal-structural analysis model 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). At the start of the task, launch ANSYS Workbench with `C:\\Program Files\\ANSYS Inc\\v261\\Framework\\bin\\Win64\\RunWB2.exe`.\n\nPhysical problem: A straight steel bar is axially restrained and subjected to a uniform temperature increase. Coordinate system and geometry: - Use the global Cartesian coordinate system. - The bar length is along the X direction. - The bar occupies: - 0 ≤ X ≤ 100 mm - 0 ≤ Y ≤ 10 mm - 0 ≤ Z ≤ 10 mm - The left end face is X = 0. - The right end face is X = 100 mm. Model parameters: - Block size: 100 mm × 10 mm × 10 mm - Material: linear elastic steel with thermal expansion properties: - Young's modulus E = 210000 MPa - Poisson's ratio ν = 0.3 - Coefficient of thermal expansion α = 1.5e-5 /°C - Element type: SOLID185 - Mesh: global element size 5 mm Thermal condition: - Set the reference temperature for thermal strain to 20 °C. - Apply a uniform body temperature of 100 °C to the entire bar. Structural boundary conditions: - Restrain axial expansion by applying UX = 0 on both end faces: - X = 0 - X = 100 mm - Add only the minimum additional constraints required to prevent rigid-body motion in 3D space. For a solid model, this requires fixing translational degrees of freedom at strategically selected nodes on the same end face, for example: - At node (0, 0, 0): fix UY = 0 and UZ = 0. - At node (0, 10, 0): fix UZ = 0. - Do not fully constrain the lateral surfaces. Analysis type: - Static structural analysis with thermal strain. - The temperature field is applied as a uniform body load for thermal strain calculation. Save requirements: - Use C:\\Users\\user\\Desktop as the ANSYS working directory. - Save the database file as: C:\\Users\\user\\Desktop\\apdl_thermal_stress.db - Save the structural result file as: C:\\Users\\user\\Desktop\\apdl_thermal_stress.rst", | |
