Hi,



I'm trying to run a case in which a flow drags particles around a prism.
After a few time iterations, I have wrong volume fraction. For example :
"alpha.particles volume fraction = 0.0152091 Min(alpha.particles) = -0.0201645 Max(alpha.particles) = 1.21005"


Moreover this case "runs" for few iteration with low velocity. I'd like, at the end of the day, make it run with high velocities (in terms of km/s).


I already tried to reduce the pressure tolerance and the drag model residual, but nothing satisfying.


Does anybody know what can I do or what is wrong with my case ?


Thanks !
