Jan Stránský proposed the following answer:
> I do not want the spheres to move out of the boundary

in both cases, you will have to use different engines, namely Bo1_Facet,
Ig2_Facet_Sphere, see [2]

> Using [1] creates a default set of facets and combines them to form a
cylindrical boundary of the prescribed dimensions. Isn't it?

yes

>On the other hand in [2], the user is creating facets (using vectors)
and then combining them followed by application of pre defined
stresses(confining pressure). My question here is can this operation be
performed like in [1]? that is using a simpler way to create facets and
then applying stresses.

yes, you can use facetCylinder and then apply force on resulting facets
in the same way as in [2]

> In short, I am looking for a simpler way to perform the application of
laterally confining pressures.

Do you really want active confining pressure? Wouldn't static boundary
be enough? At least for beginning, I would try the static boundary..

cheers
Jan
