Meshing tips: 1. Understand the Problem Physics Knowledge: Identify regions with complex flow patterns and plan your mesh accordingly, especially for turbulent flows where boundary layer resolution is crucial. 2. Choose the Right Meshing Technique Structured vs. Unstructured: Use structured meshes for simple geometries and unstructured meshes for complex ones. Consider hybrid meshes for different regions to balance accuracy and cost. 3. Prioritize Mesh Quality Aspect Ratio and Skewness: Keep aspect ratios close to 1:1 and avoid high skewness (above 0.5) to ensure accuracy and convergence. 4. Refine Critical Areas Boundary Layers and Gradients: Use finer mesh in boundary layers and high-gradient regions. Consider Adaptive Mesh Refinement (AMR) for automatic refinement. 5. Use Inflation Layers Boundary Layer Resolution: Apply inflation layers with a smooth growth rate (1.2 to 1.5) to accurately capture boundary layers. 6. Simplify Geometry Remove Small Features: Simplify geometry by removing irrelevant features and use symmetry to reduce computational domain size. 7. Conduct Mesh Convergence Studies Mesh Independence: Ensure your results are mesh-independent by refining the mesh until key outputs stabilize. 8. Utilize Automatic Tools Automated Meshing: Start with automated tools but refine critical areas manually using local mesh controls. 9. Use Parallel Meshing for Large Models Efficiency: Leverage parallel meshing to speed up the process for large or complex models. 10. Iterate and Improve Iterative Process: Start with a basic mesh, run simulations, and refine based on solver feedback and convergence behavior. These streamlined tips will help you create a well-optimized mesh for accurate and efficient simulations.
