Problem with my pisoFoam cases
 

Hi everyone,
I am running a Newtonian/non-Newtonian case with pisoFoam solver. The case is just a simple rectangular domain with periodic boundary condition in y direction. The periodic BC has been implemented by fvOption and velocity 10 as desired Ubar. However, when I run the Newtonian or non-Newtonian (Herschel-Bulkley) cases, I see a problem with pressure field. Hence, can anyone help me by looking at the attached zip file? I also attached the images for pressure field in Newtonian and non-Newtonian cases.

Cheers,
Mo
