I am modeling a siphon using Flow 3D. The problem is that the water starts coming from downstream side at the beginning of simulation which is not logical.


Xmin. = Volume Flow Rate
Xmax. = Specified Pressure (with fluid height)
Ymin. = Symmetry
Ymax. = Symmetry
Zmin. = Symmetry
Zmax. = Specified Pressure ( F = 0)

I am also attaching ".jpg" file of the frames.
