Inlet velocity is not constant at all?
 

Hi all Foamers.

At the moment i follow a simulation like this clip : Bubble flow within a water domain

The point is when i visualized my result , the velocity at inlet is not constant at all ( = 0 ) even i already set BC for inlet of U is fixedValue with uniform (0 0 0). And in kinematicCloudProperties I also set the samething . The solver i used is MPPICInterFoam with openFOAM v1606+

So what would lead to this problem, please help me !

Any advice are highly appreciated,

Thank you !!
