Bruno Chareyre proposed the following answer:
The consolidation stage is supposed to be isotropic. If it is isotropic + constant volume then there is really nothing happening, the boundaries do not move, and the stress is constant.
"But the stress must be increased", you may think. Yes, if you think in terms of total stress on a saturated sample in lab tests, but you don't simulate the saturating fluid, so what you have for stress in the simulation should be understood as effective stress. And of course (do you agree?) the effective stress is not changing during a "U" consolidation.
