Mesh Quality Metrics

Mesh quality affects accuracy, convergence, and solver robustness. Poor-quality elements can distort strain fields and degrade numerical conditioning.

Common mesh quality metrics include:

• Aspect ratio.
• Skewness.
• Warpage.
• Jacobian quality.
• Minimum and maximum element angle.
• Element size transition rate.

Quality thresholds depend on element type and analysis objective. Critical regions such as load application areas, constraints, holes, fillets, and contact interfaces usually require higher mesh quality and finer resolution.
