Comparison of Dynamic Mesh Adaptation Methods

Comparison of Dynamic Mesh Adaptation Methods

Weiyang Lin, Steve L. Karman

For small rotations, all the three methods have good performance. Here is the video for the first method (optimization-based):

The following figures show the extreme cases, where the airfoil is rotated for 180-degrees. 

1. Optimization

2. Winslow Smoothing

3. Linear Elasticity
