Descripción de la oferta
I need an ANSYS CFD specialist to reproduce a reference simulation workflow for three geometric cases using ANSYS 2024 R1, SpaceClaim, Fluent Meshing, and Fluent. The geometry consists of two vertically stacked, coaxial cylindrical fluid regions. The required dimensions are in metres: Case 1: r = 250, r1 = 550, h = 300, h1 = 800 Case 2: r = 300, r1 = 500, h = 250, h1 = 850 Case 3: r = 250, r1 = 550, h = 250, h1 = 850 Here: - r is the radius of the circular outlet on the top. - r1 is the radial distance from the outlet edge to the outer wall. - h is the lower-region height. - h1 is the upper-region height. - Outer radius = r + r1 = 800 m for every case. - Total height = h + h1 = 1100 m for every case. SpaceClaim requirements: - Create two separate cylindrical fluid bodies with shared topology at their interface. - Outer cylinder diameter: 1600 m. - Outlet diameter: 500 m for Cases 1 and 3; 600 m for Case 2. - Create and name the boundary surfaces: ground, inlet, side, outlet, and top. - Save a separate SpaceClaim geometry file for each case. Fluent Meshing requirements: - Use the Watertight Geometry workflow. - Use metres as the geometry units. - Surface mesh sizes: minimum 0.01 m and maximum 10 m. - Assign ground as wall, inlet as velocity-inlet, outlet as pressure-outlet, and side/top as symmetry. - Add 30 boundary-layer cells on the ground with growth rate 1.2 and transition ratio 0.272. - Generate the volume mesh and improve its quality. Fluent solver requirements: - Configure a transient simulation. - Apply the required cylindrical inlet-velocity components using the provided velocity UDF. - Use a 0.01-second time step, 1,000 time steps, and a maximum of 50 iterations per time step. - Initialize the solution and save the completed case/data files. I will provide a reference video showing the required workflow. Please follow it closely and report any missing input, particularly the velocity.c UDF file or the required turbulence model, before completing the solver setup. Required deliverables: - Three SpaceClaim geometry files. - Three generated Fluent mesh files. - Three fully configured Fluent case/data files. - Mesh-quality screenshots or report. - A short description of the settings used for each case.
