Recommend structured grid deforming algorithm
 

Hi,

I've a FVM 2D structured NS solver and now there is a need to handle problems whereby the grid moves/deforms.

I've incorporated Batina's spring grid deforming algorithm and it works. However, it cannot handle large deformation (airfoil rotating by 20deg) and it is meant for unstructured grids.

Can anyone recommend a better algorithm meant for structured grids, which can handle bigger deformation?

thank a lot!
