Jan Stránský proposed the following answer:
> actually it didnt bounce back the minute interaction happens, part of
sphere still went through wall then back

in DEM, (basically) a repulsive force is computed w.r.t overlap. So the sphere MUST go "through wall" to get some repulsive force to "go back".
Increase stiffness even more to reduce the overlap.

> what i really need is a 'ground' object

If increasing stiffness does not give you what you want, then please
define "ground" more specifically.

cheers
Jan
