About
Structured meshes use regular grid patterns with predictable connectivity. Ideal for simple geometries with high solver efficiency.
Unstructured meshes use triangulation to adapt to complex boundaries. More flexible but with variable element quality.
Key Equations
Aspect Ratio: \( AR = \frac{L_{max}}{L_{min}} \)
Optimal: AR ≈ 1, Acceptable: AR < 3
