      Hello everyone，

      I'm running an internal pipe flow simulation with one inlet and one outlet and  setting inlet and outlet as translational periodic boundary condition.  I think it has converged and residual polt is showing below.

      And I want to check the mass conservation but it didn't show any value of outlet which really confuse me a lot.

      Does anyone can explain this situation?

      regards

      PS: periodicity mesh is made in Fluent Meshing. In "update boundary" task, inlet is "periodic" and outlet is "shadow".
