Hi
I'm trying to test the interMixingFoam solver when studing gravity currents. So I took the tutorial example but changing the initial alpha fields. The initial condition is a horizontal free surface, and two separated phases, with different densities (I attach the whole example). I was expecting to see the gravity currents due the difference in density, but both liquid phases behave as they have the same properties. What could it be wrong? Thanks! Martin |

Dear Martin,
There's indeed a bug in interMixingFoam. The solvers incorrectly assigns the properties of phase 2 to phase 3, so both are identical, preventing the development of any density current. I've posted the bug-fix in this thread: http://www.cfd-online.com/Forums/ope...rents-bug.html Best regards! Nicolas |
