particle count on walls (Rocky)

      Hey, I plan to set up a few simulations to study particle adhesion on the surface of a bluff body. I tried setting particle time selection on Rocky to calculate particle count for particles that bounce or stick to a surface, I would want to run a 1-way coupled simulation using flow file from ansys fluent. This is what I see on rocky’s side. I don't understand how I can use this to count the number of impinged particles on that wall.
      I have a ‘.f2r’ file from Fluent, I just need to use with ROCKY, i did go through the sdk module to see if something might be of help but i dont think i can use any of it. Please give me your opinion on how I can do this. Thanks,

      Hello Kiran, 

       

      Considering that you created an User Process (cube, cylinder, plane or polyhedron) around the wall, and from that you created the Particles Time Selection, you might use All for Domain Range, so what you will see in this Selection is the last particles positions before leaving the User Process region, for the whole simulation time. You will visualize but it won't help you to count the particles that stick to the wall.

       

      To count the particles that stick to the wall, create another User Process, close enough to the wall that does not encompass the particles that bounce off it.

      Then, go to the last output. If you hide particles and the other User Processes, the only thing you should see is the particles that stick to the wall. 

      From this new User Process, check the particles number (you might use the prepost scripting to check this Data). 

       

      Best regards,

      Lucas
