there is a way in blender to simulate a stone impact on a grid ( with the deformation of the grid)?
not currently, well not physical simulation
you can try a wave effect in the object buttons
Wasn't something going on with softbodies in the tohopuu-project. I guess it won't be long before we see these in bf-blender.
AFAIK Ton is working on it.
From Ton's CVS-log.
" 1) Curve deform
Works simple as expected, but keep track of the rotation axis
in F7 buttons (Track X Y Z)
Only Mesh deform supported now.
- centralized deformation calls in curve_modifiers() mesh_modifiers()
etcetera. Here also other effects can be added like wave. Now the
evaluation order is fixed, but should become optional. It also doesnt
use the Displist anymore as deform-input. That latter part is unfinished
This code also is used for Hooks and will be needed for softbody
