Grouping is a nice technique used in VF radiation method that reduces the number of control points based on node distance
In case of High shear of deformation, a high number of groups is required
A simple and smart way is to split the deformation surface into several sub-surfaces so that more control point are attached to target surface
2 RBF kernel method exist inside scFLOW
- Thin plate
- More precise
- Wendland C2 (default)
- More stable
