Question #703284 on Yade changed:
https://answers.launchpad.net/yade/+question/703284

    Status: Open => Answered

Bruno Chareyre proposed the following answer:
Q1. " could the setting of pressure be applied by flow.imposePressure()?"
Yes, it could.

Q2. Yes.

Q3. Take the average of the pressure in all pores?

Q4. It is very unclear what it is since a consolidating volume is never homogeneous (first problem), and the stress definition at the microscale is assuming a system of forces in equilibrium (not the case here since there are drag forces not counted in the stress, second problem).
That's why I would really refrain from simulating consolidation with periodic boundaries.
