I was trying to reproduce a multiphaseEulerFoam tutorial case that happened in 2D into 3D. The original case is located at

$FOAM_TUTORIALS/multiphase/multiphaseEulerFoam/RAS/bubblePipe

this case is simulating 3 phases (air1 air2 and water). the air1 and air2 is classified as bubble in phaseProperties and the water is continuous phase.



then i modify the case blockMeshDict so the case geometry would be 3D. but when i tried to run the simulation, the air bubble would not move or just concentrated in specify region, represented in this picture below.




meanwhile i was expecting an output like this one from bubbleColumn tutorial that located at

$FOAM_TUTORIALS/multiphase/multiphaseEulerFoam/RAS/bubbleColumn

like this one below


and by the way this is my case in there is something wrong with my setup


bubble0702.zip


What should i revise/change from my case so it simulate the case like the second picture but with three phases?(first is water, second is air1, and third is air3)

my goal is to simulate advection of the phase air1 and air2 so it can move in the continuous phase(water). Thanks in advance
