Hello all,

I'm trying to simulate transport of water droplets in air through small bended pipe. I'm using InterFoam laminar solver like it is in DamBreak tutorial.

During simulation I've faced with one important problem. After I start to supply water at inlet in some time it starts to appear in another parts of the geometry but physically water did not reach these places. It starts to appear with lower scalar value and grows in time (like it is on the picture). Mesh is polyhedral. Numerical settings are like in DamBreak tutorial. Only scheme for div(rho*phi,U) have been switched from "Gauss limitedLinearV 1" to "Upwind". And no errors during simulation.

Has anybody faced with such problem? I would appreciate any suggestions from your side and thanks a lot in advance.
