Strange observation with icoUncoupledKinematicFoam
 

Hi Foamers,

I am doing particle simulation with icoUncoupledKInematicParcelFoam in a bifurcating tube with one inlet and two outlets. 10,000 particles are injected using manual injection with zero initial velocity and also steady state velocity field is pre-defined.

I can observe that particles are not following fluid streamlines. As a result I am not getting correct results. Please see attached image below. The image clearly shows particles are not following fluid streamlines. Can anybody explain this ? and how to fix this?

Regards,
Mayank.
