InOut: added line to print periodic pressure; Simulator: adding periodic algorithm to invA and ETilde inside assemblePBCNew. This step was taken to try assuage the problem with pressure convergence, however, nothing changed for now. Also, some lines came into unCoupledPBCNew, but the problem is not still this. Even with betaFlow only, the pressure has difficulties to converge. Problem seems not to be in assemblePBCNew, neither unCoupledPBCNew.
