Count particles captured by Stick-to-wall BC

Hi!

I am simulating the deposition of particles on a cylinder. On the cylinder's surface, I use the 'stick-to-wall' boundary condition. For my analysis, I need to know the number of particles captured by the cylinder. Thus, my question:

How can I get the number of particles, which deposited on the cylinder?

Cheers!

I found a solution:

In the *.out-file the solver writes

Code:

 ======================================================================
                          Particle Diagnostics
 ======================================================================

 +--------------------------------------------------------------------+
 |                      Particle Fate Diagnostics                     |
 +--------------------------------------------------------------------+
 | Particle type          | Fate type                       Particles |
 +--------------------------------------------------------------------+
 | particle               | Entered domain                :         1 |
 |                        | Continue from last time step  :        22 |
 |                        | Waiting for next time step    :        23 |
 |                        | Wall particles                :         1 |
 +--------------------------------------------------------------------+

Thus, the 'Wall particles' is the number of particles, which stick to the wall.
