Dear Jan,

Yes, deleting this sentence will allow the simulation to continue. If not, an error will be reported, and the particle will move around the periodic boundary after modifying the particle’s position coordinates. However, I found a new problem. If I increase the number of particles and the number of CPU cores, it will cause new problems in MPI communication, such as the number of particles will decrease a little, or the following error [ubuntu:14564] [[15031,0],0] ORTE_ERROR_LOG: Data unpack would read past end of buffer in file util/show_help.c at line 507,is this related to the fact that I no longer transfer these particles to the neighboring block? At present, I am still learning MPI related knowledge, if it is solved, I will continue to share it.
