Boundary condition floworks

Boundary condition floworks

(OP)
Hi,
for my master test I have to do a little flowsimulation on a draghead.
Now, I have to set the boundary conditions, but i only have the pressure on the inlet (that will be te inveronment pressure) and the pressure on the outlet, where there will be a vacuum by a sucking pump.
When i set this as the parameters, i got negative pressures, what i think is a little bit strange.

Can anyone tell me if it's possible to make the simulation just with the two pressure conditions or what i have to do to make it wright.

I setted up the general conditions, maked the lids, setted the boundary conditions en clicked on run.

Thx in advance.
