In Mesh Settings, Average Element Size is defined how?
Answer: As a fraction of the model's bounding box size
Average Element Size is a fraction of the model's overall size; smaller values give a finer mesh.
What does the Grading Factor in Mesh Settings control?
Answer: The maximum size ratio between neighboring coarse and fine elements
The Grading Factor limits how fast element size changes between neighboring regions.
What is the purpose of Local Mesh Control?
Answer: Refine the mesh on selected faces or edges
Local Mesh Control assigns a smaller element size to selected geometry, such as fillets with high stress.
Which option lets mesh elements follow curved geometry for better accuracy on fillets and holes?
Answer: Create Curved Mesh Elements
Curved Mesh Elements follow arcs and curved surfaces more closely than straight-edged elements.
What is the goal of Convergence Settings (h-refinement)?
Answer: Refine the mesh in steps until results stop changing beyond a set percentage
H-refinement refines the mesh in high-stress areas until the change in results falls below the stop criteria.
Which plot shows whether the selected result is stabilizing over refinement steps?
Answer: Convergence Plot
The Convergence Plot graphs the chosen result over each refinement step.
Stress at a perfectly sharp inside corner keeps rising each time the mesh is refined. What does this most likely show?
Answer: A stress singularity
Sharp re-entrant corners create singularities where stress grows without limit as elements get smaller.
