Dear all,
For the damBreak Case (~/OpenFOAM/OpenFOAM-2.2.0/tutorials/multiphase/interFoam/laminar/damBreak), I simply modified the right boundary wall into an atmosphere boundary to let water flow out of the domain. Besides, I changed the direction of gravity to simulate a 45-degree slope rather than a horizontal bottom. The result shows that after the water hits the right boundary (atmosphere), some water just flow out (go through the right boudnary), but there is some water reflected back (please see the attached figure). Is this due to numerical error? Your comments are highly appreciated. Cheers, xlibp |
