[flow_CH]

Hi.

I am modeling a flow with two inlets (up for air and down for water). My model lenght is 2 meters, and 1 meter Width that it is going gradually small.( 1 meter in inlet and 0.9 meter in outlet). The height of water inlet is 0.024 m and velocity is 3.89 m/s
The boundary condition is velocity inlet (for two inlets)
The top of model boundary is pressure inlet and outlet is pressure outlet.
I have very strange problem. In the starting of solver, and after convergence too, the static pressure of water inlet and downstream of inlet is very large numbers. (like 4e3 Pa). In bottom of water inlet, there is high negative static pressure too.
I am very confused. I tried other boundaries but pressures still is high.
Other parameters like velocity is good.

Thanks
