"instruction": "Complete a 2D laminar Couette-flow analysis using ANSYS Fluent via the Command Line Interface (CLI). To start ANSYS Workbench, run `C:\\Program Files\\ANSYS Inc\\v261\\fluent\\ntbin\\win64\\fluent.exe -g` (version/path may differ on your machine).\n\nPhysical problem: Two-dimensional shear flow of water between two parallel plates. Coordinate system and geometry: - Use a 2D planar model. - Use SI units in Fluent. - The channel length is along the global X direction. - The channel height is along the global Y direction. - The domain length is 100 mm, equivalent to 0.100 m. - The domain height is 2 mm, equivalent to 0.002 m. - The computational domain should occupy: - 0 ≤ X ≤ 0.100 m - 0 ≤ Y ≤ 0.002 m - The bottom wall is the boundary at Y = 0 m. - The top wall is the boundary at Y = 0.002 m. - The left boundary is at X = 0 m. - The right boundary is at X = 0.100 m. Boundary zone names: - Name the bottom wall boundary: bottom - Name the top wall boundary: top - Name the left boundary: left - Name the right boundary: right Model parameters: - Fluid: water-liquid - Use constant material properties: - Density: 998.2 kg/m³ - Dynamic viscosity: 0.001003 Pa·s - Mesh: - Structured quadrilateral mesh - Use sufficient resolution across the channel height to resolve the linear velocity profile. Boundary conditions: - Bottom wall: - Stationary no-slip wall - Top wall: - Moving wall - X-velocity = 1.0 m/s - Y-velocity = 0 m/s - Left and right boundaries: - Use symmetry boundaries or a periodic pair. - If using a periodic pair, set zero pressure drop between the paired boundaries. Solver setup: - Solver type: pressure-based - Time setting: steady - Flow model: laminar - Pressure-velocity coupling: SIMPLE - Spatial discretization: second-order schemes where applicable - Initialize the solution and iterate until convergence. Save requirements: - Use C:\\Users\\user\\Desktop as the working directory. - Save the Fluent case file as: C:\\Users\\user\\Desktop\\couette.cas - Save the Fluent data file as: C:\\Users\\user\\Desktop\\couette.dat",
