Particles getting deleted in DPM model

Je5u5 · June 1, 2016, 14:21

Hello i have built a model of a 2D mixing tank, with a moving wall inside that moves in a sinusoidal velocity up and down.
i am now trying to add particles to the tank to see their paths and see at what conditions they group the best.
this is a transient model
and after the first timestep i see in the TUI that fluent decides to delete the particles after the 1st timestep iterations are finished and the 2nd begins.

any one have an idea why this might happen?

p.s
i used the stochastic tracking model and fluent spray collision algorithm.
is this have something to do with the program deleting them?

Here is an image of whats happening.
it happens when i try to turn on collision model in fluent DPM
please help me

Hello
i just realized that DEM and collision model can not be used with dynamic mesh.
is there any way to use the velocity field created by the solver with the dynamic mesh, and later implent the particle movement and the collision models?
