Recommend structured grid deforming algorithm
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!
