Geometry & Fluid Domain Preparation

Import and clean CAD geometry using ANSYS SpaceClaim, extract fluid volumes, remove small features, create enclosures and bounding boxes, and define named selections for inlet, outlet, and wall boundaries.

CFD Meshing (Fluent Meshing)

Generate poly-hexcore, tetrahedral, and polyhedral meshes using Fluent Meshing, apply inflation layers for boundary layer resolution, set sizing functions, and assess mesh quality with skewness and orthogonality checks.

Physics Setup & Turbulence Models

Configure solver type, enable energy equations, select turbulence models including k-epsilon, k-omega SST, and LES, define fluid material properties, and set operating conditions for incompressible or compressible flow.

Boundary Conditions & Initialisation

Set velocity inlet, pressure inlet, pressure outlet, wall, and symmetry boundary conditions, assign thermal and turbulence parameters at each zone, and initialise the flow field using hybrid or standard initialisation methods.

Solution Controls & Convergence Monitoring

Configure pressure-velocity coupling schemes (SIMPLE, COUPLED), set under-relaxation factors and discretisation methods, define convergence residual criteria, and monitor lift, drag, mass flow, and temperature surface monitors during iteration.

Results Post-Processing (CFD-Post)

Visualise velocity vectors, pressure and temperature contours, streamlines, wall shear stress, and turbulent kinetic energy using ANSYS CFD-Post, generate XY plots, calculate drag and lift coefficients, and export animations for reporting.
