Hi,
You are right and the reason for that is that a periodic problem has no 
boundary, hence no boundary condition.
bndCondIsPressure=[X,X,0,0,X,X] is ok but you need to impose the pressure in 
one internal pore to fix a reference value (arbitrary).
Adding a constant pressure to a periodic pressure field still results in a 
valid solution. No unique solution <=> the linear system reflecting the Stokes 
problem is not inversible if no pressure is imposed anywhere, then crash.
