Soheil Safari gave more information on the question:
Dear Jan,

Thank you very much for your kind reply and valuable information as
always.

I changed these options but it did not work:
1- Reducing the “damping=0.4” value
2- Reducing the “unbalancedForce() < .05” value
3- using a higher cylinder (it works for larger particles, but not for small ones)

Please let me know how I can use a "semi-permeable" wall as you
recommend. (masked such that it does not contact with spheres going
down, but does contact with those going up (preventing them from
bouncing out))

Also, what should I do for the below options?
- contact law damping
- numerical integrator damping

I really appreciate any help you can provide.

Regards,
Soheil
