Hi all,

I am aware that in the customization manual there are some examples of looping macros including one to loop over all particles in a cell. But I was just wondering if there is any way of defining a certain radius around let's say a cell, where the tracked particle is currently located, and then loop over all particles that are located within that defined radius? May be we can identify the cells that fall withing that radius and then extend our looping macro to go over multiple cells, instead of just one?

Thanks a lot for your help in advance.

With best regards
Hasan
