Boundary condition for external flow

I am simulating the flow in way of after body of ship.
To make efficient modeling,I just modeled it as after body of ship.
also the motion of afterbody was made as oscillating vertically.
The detail description of sheme is as below.
In this modeling, I have some question.
I set up the inlet as velocity inlet and the outlet as pressure outlet.
however when I run the model, I found some convergence error as I attached.
and there is some message that reversed flow are existed in outflow.
so I am wondering my boundary condition is not correct or not.
and Should I change the boundary condition from pressure outlet to outflow?
If anyone have some good idea, please let me know.
It will be very appreciated.
Everybody has a good day~
