The prompt
Create a precision, parametric cyclone separator for ANSYS Fluent CFD, in mm. Model the solid shell and a separate, continuous internal air-fluid volume. All wetted surfaces must be smooth, connected and correctly formed. - Cylinder: 100 mm internal diameter × 150 mm high. - Cone: 250 mm high, tapering from 100 mm to 37.5 mm internal diameter. - Tangential inlet: hollow rectangular duct, 100 mm long, 20 mm wide × 50 mm high. In top view, its centreline must be tangent to the cylinder—not radial. Boolean-cut a matching opening through the sidewall so the duct opens directly into the cylindrical chamber’s annular air space. No solid block, cap or wall may obstruct it. - Vortex finder: centred, hollow tube, 50 mm internal diameter, extending 50 mm below the roof into the chamber; open at both ends. Continue it 100 mm above the roof as the clean-air outlet. - Dust outlet: centred, hollow tube, 37.5 mm internal diameter, extending 50 mm below the cone; open at the bottom. - Keep the chamber roof closed except for the vortex-finder penetration. The inlet must connect to the chamber—not directly to the vortex-finder tube. Air must swirl in the chamber, then exit through the vortex finder; dust exits through the cone outlet. - Use nominal 3 mm shell thickness. Avoid unnecessary fillets or small details. - Extract a watertight, continuous internal fluid volume containing the inlet, chamber, cone, vortex-finder passage and dust outlet. Check for gaps, blocked openings, disconnected regions and non-manifold faces. - Create separate selectable boundary faces/named selections: "INLET_VELOCITY", "CLEAN_AIR_OUTLET", "DUST_OUTLET", and "CYCLONE_WALLS". - Provide an isometric view, top view, dimensioned front view and a section/cutaway proving the inlet connection and hollow passages. - Keep dimensions editable. Export the solid shell and fluid volume separately as STEP if supported.
