hello all,
I was going through the internal codes of Liggghts and found that tag and mask variables are set for each particle. can anybody kindly tell me what are those? As far I understood is the tag is the unique id for each particle and the mask is the processor number in which a particular particle's information is stored. kindly correct me if I am wrong.
thanks in advance.

Best,
Tarun

tag is used for particle-IDs, mask is used for group-IDs
