hello everyone

Now, I am simulating a channel flow with a gate on it and interFoam is chosen to solve it. Water evaluation is fixed in the downstream section. I have tested the fixedValue (the value is 0) and zeroGradient of pd in the outlet boundary, but the water evalution changes with the varying of inlet condition. I don't know how to solve it. please help me.

thanks in advance
