Three phases problem in multiphaseInterFoam
I created a three phase multiphaseInterFoam pipe simulation. I have three phases (air, water and ketchup) in a pipe.Initially, air and ketchup (on the bottom of the pipe) is in the pipe then water comes in and should rinse the ketchup away. My problem is that the simulation collapses after a couple of iterations whereas when the density and viscosity of ketchup is chosen small then the simulation runs well. I think it could has something to do with the pressure. Has anybody an idea, hint or even the knowledge to solve the problem?
