Question #249377 on Yade changed:
https://answers.launchpad.net/yade/+question/249377

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Cyndie,

Peri3dController has to be used on periodic packings, so according to your
description not for your case.

Since your goal is zero shear stresses, standard triaxial engines should be
ok, but I am not experienced user of them so you have to wait for others to
answer

cheers
Jan
