Lesson 13 Adaptive Meshing
Topics
Why and What is Adaptivity?
What do FEM results depend on?
1. Mesh
2. Type and order of the elements used (Draft or High quality)
3. Other phenomena (numerical errors, modeling errors etc.)
What is our Goal? Is it just to obtain a solution?
Make sure our results are close to some defined accurate solution. (typical parameter is strain
energy density)
How to achieve it?
1. Modify and refine the mesh topology
2. Modify the “order” of elements
Lesson 14 Large Displacement Analysis
Topics
▪ Surface contact
▪ Contact analysis with the large displacement option
▪ Evaluate mesh adequacy for modeling bending stresses
