haze_1986 is on a distinguished road
Dear all,

I am currently working on a adding a momentum sink to a solver but I noticed that the velocity results at the inlet boundary are different from what I have specified at the boundary as the calculation proceeds with time. It got lower than specified at steady state. Correct me if I am wrong, but I suspect I have applied the sink terms to the value at the boundary inlet as well. Is there any way I can prevent the sink terms from getting applied to the boundary? Any past examples that I can refer to?
