I'm analyzing a cylcone separator with air and solid particles.

I have problems with calculating and displaying the particle trajectories. It says in the result summary box that their 'fate' is "maximum time step". However, the 'residence time' for all 20 particles is between 1 and 2 seconds. I have specified the maximum time to 3600 seconds on the settings tab when i set up the particle study.

In help it says:

"Maximum time. Stops the particle's trajectory when the particle traveling time has reached the specified maximum value."

Why does it stop before it satisfies this criterium? Have I overlooked or misunderstood something?

Se attached for pictures of cyclone and dialog boxes.

Thanks!
