asbj1107 is on a distinguished road
Im trying to set up a study where I empty a bottle with a hole in the top, to get air in, and one in the buttom there the fluid have to come out. The only force reacting on the fluid is gravity. I try to run the interFoam solver, but the deltaT keep getting smaller and smaller (I stopped it the it hit a e-14 value - see pic). I make the setup based on the damBreak tutorial. I do not make blockMesh because the bottle is round. I have not touched the fv.Solution other than trying to change the tolerances. Am I doing something totally wrong or am I just too impatient?
I have attachted a picture of my p_rgh, U, alpha.water, transportProperties, a sketch of what i try to simulate and a screenshot of the solver when stopped.
