Problem of water from nowhere

nels0n · July 26, 2016, 08:32

Hi,

I'm simulating from a restart simulation with no problem a flow over a flood evacuator in Flow 3D v11.1 and I set the following boundary limit:
xmin: Specified pressure, Stagnation pressure, Fluid elevation
xmax: Specified pressure, Stagnation pressure,
ymax: Specified pressure, Stagnation pressure, Fluid elevation
ymin: symmetry
zmin: symmetry
zmax:symmetry

I've already done this simulation for a case and I obtained result with no problem.
I keep the same setup than before whith this time the bottom of the gate 0.3m higher but I obtain a sort of waterfall from the back of the right gate whith no physical explanation. No leaks are appearing, and fluid elevation is set 0.5m above the restart simulation. I've attached a picture of this problem after 140s of simulation time

Thanks for your answer

Cant see your picture. Also, share your prepin if you want me to have a look.
