Mesh quality is one of the most critical factors affecting the accuracy of your simulation results. In this article, we share tips for creating high-quality meshes in Ansys.
Why Mesh Quality Matters
A poor-quality mesh can lead to:
- Inaccurate results
- Convergence problems
- Longer solve times
- Numerical instabilities
Key Mesh Quality Metrics
- Aspect Ratio: Keep below 5:1 for most applications
- Skewness: Target values below 0.8
- Orthogonality: Values closer to 1 are better
Best Practices
- Start with geometry cleanup to remove small features
- Use inflation layers near walls for CFD
- Refine mesh in areas of high gradients
- Perform mesh independence studies
- Use appropriate element types for your physics
