Jan Stránský proposed the following answer:
Hi Seti,
to control confining loading, you simply set different value of force to
the facets [1].
In the script, first the confining pressure is prescribed and then axial
deformation is prescribed (i.e. confining pressure is constant and axial
stress changes). But it should be no problem to add two walls at top and
bottom of the specimen, and prescribe force both to facets and the walls to
get desired loading stress (hence control confining and deviatoric loading).
Stiffness is controlled by young and poisson parameters.
cheers
Jan
