  "instruction": "Build and solve a 2D axisymmetric structural model of a thick-walled cylinder under internal pressure 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). On this machine, launch ANSYS Workbench with `C:\\Program Files\\ANSYS Inc\\v261\\Framework\\bin\\Win64\\RunWB2.exe`.\n\nPhysical problem: Axisymmetric thick-walled cylinder under internal pressure. Coordinate system and geometry: - Use the global Cartesian coordinate system for the axisymmetric cross-section. - X is the radial direction. - Y is the axial direction. - The cylinder has an inner diameter of 50 mm and an outer diameter of 100 mm. - Therefore, model the radial domain from X = 25 mm to X = 50 mm. - The axial thickness is 10 mm. - Model the rectangular axisymmetric cross-section: - 25 ≤ X ≤ 50 mm - 0 ≤ Y ≤ 10 mm - Do not model or constrain a symmetry axis at X = 0, because the cylinder has a central hole and the axis is outside the modeled annular cross-section. Model parameters: - Material: linear elastic steel - Young's modulus E = 210000 MPa - Poisson's ratio ν = 0.3 - Element type: PLANE183 with axisymmetric option enabled - Mesh: global element size 5 mm Boundary conditions and load: - Inner cylindrical surface at X = 25 mm: apply an internal pressure of 10 MPa acting on the cylinder wall. - Outer cylindrical surface at X = 50 mm: free surface. - Axial faces: - At Y = 0 mm: constrain axial displacement UY = 0. - At Y = 10 mm: constrain axial displacement UY = 0. - Do not constrain radial displacement UX on the inner or outer cylindrical surfaces. Analysis type: - Static structural analysis. Save requirements: - Use C:\\Users\\user\\Desktop as the ANSYS working directory. - Save the database file as: C:\\Users\\user\\Desktop\\apdl_cylinder.db - Save the structural result file as: C:\\Users\\user\\Desktop\\apdl_cylinder.rst",
