Hello OF-Users
I am trying to simulate a distribution of a incompressible fluid between different two spaces and I am not sure, how should I set up the boundary condition of the outlet. The velocity for the inlet-flow is 1 m/s , and the with of inlet-face is 2 units. the width of the outlet-faces is 42 units I used this BC for the outlet: for p : Code:
outlet { type fixedValue; value 0; } Code:
outlet { type zeroGradient; } So that is why I tried to use the conservation of the mass to define the flow velocity in the outlet (0,047619 m/s) ... and I defined the pressures BC as zeroGradient ..but ... It did not help either.. In the attachment is a screen-shot of the physical domain. the fluid comes from left and go out from the right side. Any suggestion? Any help will be appreciated!
